Abstract

A novel series of autonomous phase-gain rotation/linear piezoelectric optimal sensing (APROPOS) devices, designed on a sensor structure and constructed by using the advantage of piezoelectric distributed-sensor and the incorporation of the interface circuit, is disclosed in the present invention. Several different series of APROPOS devices are proposed in the present invention. By ingeniously using the design of piezoelectric thin film, the sensor structure characteristic, the feedback control theory, the wave transmission theory, the integration of boundary conditions and the application of interface circuit, a series of vibration sensing apparatus with the filtering and frequency selection characteristics of high pass, low-pass, band-pass and band-obstruction are designed. For the point-type sensor, the applicable bandwidth of the sensor can be effectively increased. Due to its type difference and characteristic difference, the series of vibration sensing apparatus proposed in the invention can be evolved to form different kinds of vibration sensing apparatus so as to raise the applicable range of the vibration sensing apparatus. In the invention, the design method of distributed sensor is ingeniously used in the structure of point-type sensor itself such that a novel autonomous phase-gain rotation/linear piezoelectric optimal sensing device is designed. Thus, an innovative point-type vibration sensing apparatus having the convenience characteristic of point type sensor as well as even bigger freedom and wider application range than the conventional sensor structure can be created by only one time of design for the sensor structure body.

Description of the invention (2) Its function. It is worth noting that the puppet-type inductor can only obtain the structural characteristics of a single point on the object under test, and cannot directly show the dynamic characteristic curve of the entire structure. However, when the measurement range is extremely wide, the number of point sensors needed to be used will also increase. These large vibration signals will also cause difficulties in signal processing and make real-time control (rea 1 time contro 1). It becomes difficult and complicated. In contrast, since the theory of distributed sensors began to flourish in the 1980s, it has been clearly pointed out how to design and even control the induction through different surface electrode shapes and electrode polarization directions. The available bandwidth of the child. And because the electrodes are continuously distributed in space, in addition to measuring the overall vibration information of the structure under test, it can also be used to measure the uniform force on the structure. But because the uniformly distributed inductor needs to be redesigned with the structure of the measured body, its application range is mostly limited to special structures, which is easy to be promoted and applied to a variety of structures. This shortcoming is that ; The main reason for the development of the type inductor is still not as widespread and easy to apply as the point type inductor. The structure of δ mentioned by Ming is based on the patent application of the Republic of China 8 8 丨 丨 3 5 9 i ^ ί The point of origin is based on the orthogonal characteristics of the vibrational modes of the structure and the wave propagation theory, which will benefit the $ state inductor. The basic structure of uniformly distributed inductors such as the space filter is a vibration detection device with a gain function of ^ 1 to design a discrete phase. Asia introduces feedback control theory to adjust various different types of gain functions: the frequency response of a vibration detection device with discrete phases can be improved to improve the application range and performance of the vibration detection device itself. This newly invented vibration detection device with discrete phase design can itself be 505793 V. Description of the invention (3) One-point inductor is set on a structure to be measured, and the characteristics of external vibration are measured as A detection function of a frequency-selective point-type measurement device with a gain function but a discrete phase design can also be provided on a flexible structure. The structure characteristic of a measurement point on the structure is a gain function but the phases can be separated. Design of a flexible structure frequency selective measurement detection device. Piezoelectricity is a material that interacts with mechanical energy and electrical energy. It was discovered in 1880 by the brothers Pierre Curie and Jacques Curie that this kind of deformation caused electrical polarization (electrical polarization). n) The material property of the phenomenon is named piezoelectricity. A piezoelectric material undergoes deformation when subjected to a force, and the energy of this deformation is converted into electrical energy by the process of electrodeposition, and vice versa. The polyvinylidene fluoride (pVF2,

Polyvinyl i dene Fluoride)為一常用的壓電感應子材料。 PVF2是個擁有良好彈性的高分子聚合物,可承受拉力及壓 力,且擁有極高的壓電常數,故為一良好之感應子材料。 又壓電材料的壓電性具有互補特性(recipr〇cal relationship),任何型式的壓電感應子,若以電壓輸入 即可製作成為與感應子具互補特性的致動器、,本發明 利用此一互補特性來建構增益函數但相位可分立設計之 動k測舣置中感應子結構的迴授控制系統。 雖然本發明所提之實施例均以壓電聚合物pvF2為基本感應 =材料丄但本發明所提出的各種創新設計之振動檢測裝 木構’貫可適用於所有的壓電材料及各種壓電感應子掣 程,故僅修改所使用之壓電感應子材料或修改製程,實不Polyvinyl i dene Fluoride) is a commonly used piezoelectric inductor material. PVF2 is a high-molecular polymer with good elasticity, can withstand tensile and compressive forces, and has a very high piezoelectric constant, so it is a good inductive material. In addition, the piezoelectricity of piezoelectric materials has a complementary relationship (reciprcal relationship). Any type of piezoelectric inductor can be made into an actuator with complementary characteristics to the inductor if a voltage is input. The present invention uses this A feedback control system for constructing a gain function but a phase-discrete design of a dynamic k-measurement center inductive substructure with complementary characteristics.

The curves 16 and 17 in Figure 1 indicate that For example, the effect of the spatial filter of curve 13 or the traditional electronic filter on the phase of the original inductive substructure system. It can be known from the curve 16 in FIG. 1 that the spatial filter architecture introduced into the point inductor by using the present invention may not follow the cause and effect as the general electronic filter will affect the system gain. Rate to affect the phase of the entire system. The curve 22 in Figure 2 is the effect of applying the modal inductor to the point inductor. It can be clearly seen that by eliminating the effect of the first mode, its available bandwidth is 24 ratios. The permissible available bandwidth of the original substructure 2 1 is much higher than 2 3. It is worth noting that the two methods selected this time have adjustable gain response functions of the system of the substructure and may not follow For example, the traditional electronic filter needs to follow the cause-effect ratio to adjust the phase. One special case is that it is possible to adjust the frequency response characteristic of the system gain without causing the phase shift of the induction subsystem.

This window function h (X) There is value in the structure body, and it is a zero-value function outside the structure body. In this way, the expression form of wave transmission can be transformed from the finite structure ontology to the infinite domain, and then the Laplace conversion table is used for design.

Appropriate selection of the position of the design origin on the inductive substructure will select a variety of different spatial filtering effects. The following will detail the gains and phases of different characteristics of one of the series based on this design concept. The discretely designed Rainbow 4 production test device. ^ As can be seen from equation (1 5), the spatial filter is designed for the wave number domain 4 when designing, and then the dispersion relationship of equation (11) is returned to the frequency domain, and this relationship is used to achieve the inductive substructure. Control of system frequency response function. It is known from equation (1 5) that the various designs proposed in the present invention are assumed to be simply resonant in time, that is, the term of e-1 is deliberately ignored, but when designing the spatial filter, its design origin

This phase response will not change the design origin. The only thing that needs to be considered is the electrical induction object. Another value net: there will be no knot effect. It is easy to set, the measured electric power is different from the original point, and the actual performance of the waste electricity sensor. In addition, a * structure is obtained to obtain the vibration source that generates the system structure. The simple harmonic resonance in time will form a difference at each frequency. Therefore, its influence on the entire induction effect can be reconstructed by linear superposition, so What will affect the basic design and characteristics of the entire spatial filter is that when selecting different design origins, the response of the overall piezo-vibration source will have different phase shifts. The current mention is that if the design origin is deliberately selected at the vibration source , The time difference caused by the movement will cause the phase difference of the piezoelectric sensor. The signal of the vibration detection device designed with the vibration source as the design origin will not contain the difference between the location of the vibration source and the design. Therefore, under this design condition, all The completed frequency response will be nothing more than the characteristics of the induced substructure

From Eq. (15), we can know that the filter between * can be designed for the characteristic multiples of the wave ^ :.

This map translates bilateral Laplacian into a tool to design a variety of escapes: I well-made inductors For example, a hand with gain change but no phase change is an important target.

Description of Invention (14) is continuous. However, when the wave reaches the fixed end, it will have a phase transition of 180 degrees, so if the origin of the spatial filter is designed at the free end as shown in Figure 5, where 5 丨 is the spatial filter with the free end as the design origin , 52 is an inductive substructure. For waves, the spatial filter seen in the infinite domain will be an even function as shown in Fig. 6. If the fixed origin is used as the design origin in Fig. 7, where 7 ^ is a spatial filter designed with a fixed end, and 72 is the body of the inductive substructure, then the spatial filter seen by the wave in the infinite domain is an odd number as shown in Figure 8 and therefore can be used as above The mapping principle described above is used to fully apply different boundary conditions to treat the waves originally transmitted in the finite field induction substructure ontology as transmitting in the infinite domain. Figure 9 is the space constructed with the fixed end as the design origin. The schematic diagram of the filter viewed in the infinite domain, where the rough $ 91 is the schematic diagram of the wave transmission in the structure body, 92 is the schematic diagram of the infinite domain wave propagation developed from the finite field where the piezoelectric inductor is located, and curve 9 3 means that the wave comes in the structure Seeing the spatial filter ^ when thinking back, the figure clearly shows that its expansion on the infinite domain is odd. Figure 10 shows the spatial filter designed with the free end as the design origin. Curve 1 0 1 and 1 0 2 represents the interior of the body of the inductive substructure and uses Turing's principle to extend the boundary conditions to the infinite domain to view the wave propagation effect: 'From curve 103, we can see the expansion of this type of spatial filter on the infinite domain. The concept of “number by number” is an important basic design method and structure of a vibration detection device with a daily running number but a discrete phase design.

Description of the invention (19) It is an important design goal to generate the band-effect effect to reduce the effect of resonance to increase the available bandwidth. Integrating the two aforementioned design concepts, the design origin of the spatial filter has the same effect on the left and right homogenous dissipative or transmitted waves from the two sides of the design origin. The same two waves that leave the center respectively produce the same signal. The reason why the spatial filter can achieve the effect of gain on the frequency response function of the inductive substructure without changing the phase is that for the design origin, its past, present, and future information exists, so it can only To meet the design requirements of gain change without phase change. So if the spatial filter has symmetrical shapes of the effective surface electrodes on the left and right sides of the center point, then equation (1 5) can be rewritten as: q (k) = -zle3lk2-{Wip + Wrp) J f (XykX dx + + Wre )] ^, (18) bits are fsfe / JA ^ * No more, just come out. The counter is designed to set the wave filter to filter the space rate to the air frequency, which is the same as X) and the special f (the number of special phases is a function of which is extremely important. The video appliance meets the wave without filtering, and the current value is suitable for the air.

Description of the invention (23) The distribution of the dissipated wave is the same as that of the dissipated wave, and the effect of the dissipated wave will be proposed.

The characteristics of the zero point are the same as those of the primary system. The zero point of the spatial filter It is also formed by the transmitted wave, but the characteristics of its poles are the joint formation of two kinds of waves. The superimposed characteristics of the spatial filter applied by the present invention can only determine the characteristics of its poles, but its zero point must be determined after passing through points, but If each spatial filter is itself or synthesized No phase, an addition effect of the entire system will not affect the frequency characteristics of the phase response function, and at the same time does not make the original design of the spatial phase filter of invariant properties are affected.

Description of the invention (27) &gt; 0 and X &lt; 0 signals will form the required spatial filtering effect. The following summarizes the influence of each type of substrate on the frequency response function of the inductive substructure body: (a) If the surface electrode constituting the spatial filter Including e αχ or e- αχ will provide two-order poles for the frequency response function of the body of the inductive substructure. For example, the pole generated by e-wi is 1 / (y — S2).

(b) 若構成空間濾波器之表面電極中含有ej αΧ或e-』αΧ就會對 感應子結構本體頻率響應函數提供一個二次的極點 (?〇16),並會在系統中產生阻尼,如6-4\|以11(/5又)所產 生的極點為 4 α 召s/(s2 + 2as+a2)( s2 - 2as+a2)。 (c) 若構成空間濾波器之表面電極中含有χη,則代表提高 空間漶波器對感應子結構本體頻率響應函數影響之極點 (pole)的次數,如xn eiUI所產生的效應為…[(a— n+1-( a +s)n+1 ]/ ( a2 — s2)n+1 〇(b) If the surface electrode constituting the spatial filter contains ej α × or e- ″ α ×, it will provide a quadratic pole (? 〇16) to the frequency response function of the body of the inductive substructure, and it will generate damping in the system. For example, 6-4 \ | calls s / (s2 + 2as + a2) (s2-2as + a2) with a pole of 11 (/ 5 again). (c) If the surface electrode constituting the spatial filter contains χη, it represents the number of times to increase the pole of the spatial response of the frequency response function of the inductive substructure. For example, the effect of xn EIUI is ... [( a— n + 1- (a + s) n + 1] / (a2 — s2) n + 1 〇

Detection of the free end The opposite of the free end has been mentioned. The wave and the decontamination ilb are applied to this low-pass filter device with a zero-point even function. The appearance of the number of beams previously corresponds to the characteristics of the parity function wave. The wave front's free point of origin, the fixed end of the wave is the ratio of the effect on the two waves to the even function of the inductor junction detection device. As far as the rationale of the gain function is concerned, the evenness of the even function provided by the odd function can be set, but the phase can be set. Waves and waves are continuous spatial filters, and the effects in space are odd and discrete.

Description of the invention (31) Addition can automatically form a band-pass wave waver, and with the cooperation of the interface circuit, a high-pass filter can be easily constructed, and if a simply supported beam is used as an inductive substructure Because there is no dissipative wave, it is only one jk more than the frequency response function of the even function, so it is easy to construct a vibration function with a bandpass or high-pass filter at any frequency, but the phase can be designed separately. As a detection device, the present invention will use a cantilever beam as an example to propose a series of band-pass filters and high-pass filters. Therefore, on a cantilever beam inductive substructure, the same type of spatial filter is added to the free end and the fixed end, as shown in Figure 19, where the curve 191 represents the spatial filter designed with the fixed end as the design origin. Device, its mathematical expression 1 f 丨 (X) can be defined according to (1 6), the curve 1 9 2 represents the spatial filter designed with the free end as the design origin, and its mathematical expression f2 (X) also It can be defined according to formula (1 6). By taking out and adding these two signals separately, a zero point (ze r0) can be directly provided in the 'system, and the frequency gain of the interface circuit is −193 or a spatial filter is formed. The surface electrode size is used to control the relative gain of the two spatial filters designed according to the free end and the fixed end, so that the position of this zero point s can be controlled. In this way, the corner frequency of the spatial filter can be matched to produce a filter such as The bandpass filter (ba nd passfi 11 er) of the curve in Fig. 20, for example, if the surface electrode f 丨 _ (乂) constituting the spatial filter can be expressed as 丨 1 (\) +% (乂), Then a band-pass filter like curve 201 and 202 can be obtained Frequency response function, in other words, the entire system can be expressed as: Φ) = [-(Μν + (* 〇] + (&gt;% + ^ j [(^-(* s)]]), (3 3) The main purpose of σ is to adjust the design of the free end and the fixed end-

The relative gain of the two spatial filters in the description of the invention (32). It is worth mentioning that the relative increase represented by σ 'can be achieved by using the relative size of the space electrodes as discussed above. This can be achieved by the relative electronic gain of the interface circuit of the two spatial filters. Because s of the transmitted wave is jk and -jk, and s of the dissipated wave is k and _ k, both will generate additional zeros, but the corner frequency of the spatial filter can be arbitrarily adjusted before the first zero appears. And plus: t has a benefit value σ, _ Cai nose produces a vibration detection device with a gain function of band-pass filtering characteristics but a phase that can be designed separately. &quot; &quot; The signal amplification of the local pass filter should be based on the real zero point gain of Figure 21 for the purpose of amplification. The design of the wave filter is to continue the principle of the band pass filter. Connect the current amplifier (charge amplifer), and freely terminate the appliance (charge amplifer), so you can easily add a zero to the frequency response function of the sense system, (zer〇) Among them, 211 and 212 are current amplifiers respectively, and 2 1 3 is the gain value applied to the current amplifier, and the basin is to adjust the position of the current amplifier and the charge amplifier 2 ^. The curves 221 and 222 in Fig. 22 are schematic diagrams of + ancient,, ^, and phase. The entire system is expressed according to formula (3 丨): 1 pass filter state is as follows: and the synthesis of formula (32) is the same as long as the spatial filter is modulated Corner frequency check R t, (3 4) n noon and extra office 2 can design the required high-pass filter (h 彳 ^ 9 drum value, just 11 ^ π pass f · 1 and caused in the system The two zeros of the two are fixed at 6 1 1 ter), and the love of j stands upright; Shan will not make the frequency response function of the inductor before the gain mouth appears with π ',, 5, | Face-to-face

The lost signal must be replaced, in other words, an unfinished surface electrode is added to the structure, and the lost signal is added back | so that the wave can be explored in the infinite domain. 1 On the inductive substructure of a cantilever beam, as shown in Figures 23 and 24, it can be known that if the design origin is not in the center of the structure, the surface electrodes of the spatial filter cannot be fully symmetrical to the left and right, and the concept of wave propagation is applied. Since the> wave at the free end is continuous, as long as the unfinished surface electrode is pasted back and the lost signal is added back, the original space filter can be maintained as shown in Figure 25, of which 2 5 1 and 2 5 2 indicates that the originally designed space filter and the attached space filter include a piezoelectric thin layer and a surface electrode, and the π + π number on the piezoelectric thin layer constituting the two spatial filters is indicated when the original polarization The position of the applied positive electric field electrode, and the "+ π" of the two piezoelectric thin layers are facing upwards, which means that the polarization directions of the two I-space filters are the same.

At this time, you only need to multiply the current amplifier or the charge amplifier by a gain value and add them to make it on the complex plane. The imaginary part is zero, and the value of the real part is the same as the value of the original designed spatial filter, but there is no difference. The design architecture is as shown in Figure 33, where 331 is the current amplifier '3 3 2 and 3 3 3 Charge amplifier, 3 3 4 and 3 3 5 are the added gain values, so that the values of the two space filters 33 7 and 338 posted are the same as the original uncompleted space filters 3 36, but there is no difference between them. It can be easily transferred from a finite structure to an infinite field. Its meaning on the complex plane is as shown in Figure 3 4 'where 341 is a relative complex plane assuming that the phase of the spatial filter 3 36 is zero, and 342 is a signal of 337. Different phase angle due to boundary effect The signal of 3 4 3 and the signal of 3 4 2 are completely the same, but the present invention combines the application of the interface circuit and the piezoelectric material will automatically provide a 180 degree phase difference when it is pasted on the reverse side, so the signals 342 and 34 3 automatically differ. 90 degrees, plus the added gain value, so that the value of the imaginary part is 0, and the amount of the real part is the same as that of the original song. 3 4 2 Λ 5 Tiger strength can be the same.

Explanation of the invention (37) The resonance factor is that when the combination of two waves at the boundary meets the conditions of resonance, that is, the node (fixed end) and the ventral point (free end), resonance will form. From the characteristics of structural resonance, it can be known that when the transmitted wave itself has not formed a resonance condition in the structure, it forms structural resonance with the dissipated wave. Using this viewpoint, the present invention combines the design of the spatial frequency selective induction thin layer and the parity function. Applications can provide additional poles and zeros in the system to improve the performance of a vibration detection device with a gain function but a discrete phase design. It can be known from formula (1 4) that the various fourth-order systems mentioned in the present invention are synthesized by these four waves, and the signal provided by each wave can be regarded as s in the system, which can be exchanged by the parity proposed previously. It can be known that every time a common mode is reached, the effect of only one wave is proposed, generating a quadratic system, and it evolves into another wave in the next mode, so the selection of the surface electrode and the parity function can be used. The selection of the wave is to change the wave at its resonance frequency, but as mentioned earlier, when the structure reaches the resonance frequency, it will be formed when the two waves are synthesized and combined with the resonance condition, and the transmitted wave has not yet completely formed the even wave. Function or odd function, so change the parity function of the effective surface electrode, and perform the wave changing operation when the frequency of the transmitted wave forms the parity function. The basic structure of this series of vibration detection device with discrete gain and phase design is shown in Figure 4. This design method can only be used with the structural center as the design origin. The following | points are the application of this design concept to provide additional poles and zeros in the induction subsystem. (A) The surface electrode is an even function containing e —α | χ |: (a) In the odd-numbered mode, the 'dissipated wave' has a small value due to the weight of the surface electrode function ea 1x1, so its secondary system effect Eliminated, and passed

Explanation of the invention (38) Because the wave is odd, its value is zero, which forms a zero point in the system. (b) In the even mode, the dissipated wave is an odd function and its value is zero, while the transmitted wave is an even function, and its effect is retained, so the frequency range affected by the even mode is extended, but no additional 1 8 is generated. 0 degree phase shift. (B) The surface electrode is an odd function containing e-α 1x1: (a) In the odd mode, the dissipated wave becomes an odd function because the surface electrode function is an odd function of e ι | χ |, and its value is very small, so The effect of the secondary system of the dissipating wave is eliminated, while the transmission wave is changed to an even function, and its effect is proposed to form a pole of the secondary system in the system. (b) In the even mode, the dissipated wave is changed to an even function, but because the surface electrode function is e-aU1, its effect is eliminated, and the transmitted wave is changed to an odd function, with a value of zero. Zero. By applying this method, we can make a band-pass filter at a specific frequency, or add a band-pass filter to increase the available bandwidth of a vibration detection device with a gain function but a discrete phase design. (1 0) Design of window function and spatial filter: As mentioned earlier, the effect of the spatial filter can be determined by applying the basis of the spatial filter. The introduction of the concept of the window function enables the wave to be transferred to the infinite domain for discussion. , Coupled with the characteristics of the spatial filter superposition, the basis of the spatial filter can be used to design the window function, so that the effect of adding the window function on the original spatial filter design can be determined, in other words, the effect of the window function A vibration detection device that is designed together to the entire gain function but with a discrete phase design

Description of the invention (39) Centering ‘In this way, the wave propagation can be designed in the infinite domain, and the influence of the window function on the spatial filter can be determined. It can also improve the performance of the entire system. The following will introduce in detail the application of these new design concepts, one of a series of vibration detection devices designed for gain function but phase separation design. From Table 1 and Table 2 'it can be known that if there is e_a | x | in the surface electrode, the right angle frequency is at the wave number a, and it will produce a pole (p0le) of 1 / (a2-s2), which is a -40dB / DeCade's low-pass filter is actually a kind of compensator, but its structure is limited. It is impossible to make a complete surface electrode of e_a | x |, so the design concept of window function is introduced. It is found that adding a tn in front of e-αμ can increase the number of times called k, but does not destroy the characteristics of the original pole (po 丨 e). Assuming the length of the center distance boundary is a, according to the above characteristics, the following window function is selected: |, K | V — α '″, (39) make the value of the boundary at zero, and use the effective surface of e-aui to control 斗 g bucket s, xuan,.,, And pole shape to obtain the corner frequency (corner frequency) Position, the value of α frequency, so the surface charge of the spatial filter: this corner

In the description of the invention (41), under certain conditions, a phase transition system of 180 degrees at low frequencies changes the structure of the inductive sub-structure to reduce its effect on the gain function. So as long as the proper application of the benefit function but the phase can separate the characteristics of the inductor. When the vibration detection device of the previous discrete design is not important, but if the damping is known, it is only moved by the left side of the spatial filter, and it does not affect the existence of zero, so that 1 can be applied in the system at this time (1 1 The characteristic of the dispersion closeness, the zero point is referred to the extremely low frequency position, and the new concept proposed by the invention of the vibration detection device with discrete design can be used to design an additional vibration detection device. One of the proposed solutions can be obtained. The design method of the series gain function but the phase can be set is to assume that when structural damping must now be considered, the poles and zeros provided by the dispersion relationship of equation (11) only affect the frequency domain. The design of the entire spatial filter in the frequency domain However, in a damped inductive substructure, the design of the spatial filter in the wavenumber domain without a phase transfer gain function, but the phase-separated design of the vibration detection device may be affected by the damping in the frequency domain. The phase transition can be clearly found from the dispersion relationship of formula (1 1). When changing from the frequency domain to the wavenumber domain, it is negative due to the effect of structural damping. Offset on the real number axis. Suppose a spatial filter designs a dissipative wave with a zero corner frequency at α, that is, two primary systems of (s2-α2). The phase of the phase in the wavenumber domain is zero, but When it is in the wavenumber domain, it will lead to the effect of damping.

Modal inductor theory: The basic theoretical structure of the modal inductor from equation (8) lies in the shape of the surface electrode.
