Operation principle:
(1) formation of simple harmonic wave vibration
As shown in figure 24: frequency conversion motor 5, by power is passed to rotary shaft 38, stirs shifting fork bar 44, lock unit 43 is made to engage with the second gear 41, now, first gear 40 dallies, and the second gear 41 does not dallies, and power is passed to line slideway 34 by the 3rd gear the 46, second gear 41；Locking fixture 50, makes connecting rod 35 be fixed on line slideway 34, and does not install circular guideway 33；Now, crank connecting link 30 does simple harmonic oscillation.Sinusoidal wave amplitude can be rotated around rotary screw 57 by fixture 50 controlling angle, fixture 50, and fixture 50 can be fixed on line slideway 34 by fixing screw 56.Now, crank connecting link 30 produces square wave vibration.
By rolling clamp 50, changing the height of connecting rod 35, thus change the amplitude of sine wave, amplitude scale reflects the amplitude of simple harmonic oscillation accurately.
(2) formation of square wave vibration
As shown in figure 25, circular guideway 33 is not installed；Adjust fixture corner (i.e. adjusting square wave amplitude) locking fixture 5 afterwards, then adjusting the angle of line slideway 34, making connecting rod 35 be in top dead centre or lower dead center.Power is passed to gear shaft 42 by frequency conversion motor 5, now stirs shifting fork bar 44, makes lock unit 43 engage with the first gear 40, and the second gear 41 dallies, and the first gear 40 transmits power；Power is passed to line slideway 34 by partial gear the 45, first gear 40；Owing to partial gear 45 is incomplete tooth, its modulus and the first gear 40 are identical, and its number of teeth is the half of the first gear 40, so partial gear 45 rotates a circle, the first gear 40 rotates half-turn；Now, crank connecting link 30 produces square wave vibration.
(3) generation of random wave vibration
As shown in figure 26, circular guideway 33 is installed；Locking fixture 50, power passed to the 3rd gear 46 by shaft coupling, stirs shifting fork bar 44 and make lock unit 43 engage with the second gear 41 by frequency conversion motor 5, and now, the second gear 41 does not dallies, and the first gear 40 dallies；Power is passed to line slideway 34 by the 3rd gear the 46, second gear 41；The amplitude of random wave is controlled by the angle of circular guideway 33 with line slideway 34, and frequency is controlled by the rotating speed of frequency conversion motor 5；Completing above-mentioned steps, now, crank connecting link 30 produces random wave vibration.
As long as measuring the angle of line slideway 34 and circular guideway 33 in real time, the theoretical amplitude of vibration platen just can be drawn
(4) generation of other waveforms such as sawtooth waveforms
Fixture 50 is unclamped, install circular guideway 33, the angle of circular guideway 33 is manually changed by rocking bar 36, the change of circular guideway 33 angle can change the shape of vibrational waveform, this change is uncertain, except several specific positions can simulate oblique wave, other position waveforms are exactly irregular；Then fix circular guideway 33D, can obtain other waveforms various, such as, be 0 degree when circular guideway 33 and horizontal line angle, obtain sawtooth waveforms.
The present invention uses frame for movement, and parts are few, lightweight, compact to design, is taken up space relatively small, is more beneficial for indoor location and arranges；Testing stand can complete into simple harmonic wave, square wave, random wave, sawtooth waveforms exciter test；Exciting displacement, frequency is the most adjustable；Price is low, in high precision, simple operation, testing efficiency high, it uses frame for movement to replace hydraulic structure, to improve transmission accuracy, promotes testing efficiency, reduces production cost.
