Abstract
The utility model relates to a sensor for double-range force measuring sensor used for the ground quiescence experiment of the thrust of rocket motor and an electronic balance. The elastic components with a large measuring range and a small measuring range of the sensor are connected in series to form an integral structure. Clearance gap exists between the elastic component with a small measuring range and a base to meet the requirement of the measurement of a high thrust and a low thrust. Simultaneously, the utility model has the advantages of easy manufacture, convenient pasting, stable and reliable big thrust curve and small thrust curve, good repetitiveness, good return-to-zero performance, and high measuring precision.
Description
The utility model relates to a kind of strain-type force sensor, can be used for the static experiment in rocket engine thrust ground and electronic scales and engineering detecting.
Common strain-type force force transmitters all is single range sensors, has only a flexible member in the sensor, and diverse location and direction are pasted some resistance strain gages on flexible member, again resistance strain gage is formed bridge diagram.In the research that improves single chamber dual thrust solid propellant rocket thrust ratio, because designed single chamber dual thrust rocket engine thrust is than surpassing 10:1, if when measuring thrust than the thrust more than 10:1 with single range force detecting sensor, selected force cell is when satisfying the high thrust measurement, concerning low thrust is measured (thrust be less than transducer range 110), output signal is very little, and signal to noise ratio (S/N ratio) is low, and measuring error is big.In order to improve measuring accuracy, satisfy the two grade thrust Testing requirement, need to develop specially dual thrust (double-range) force cell for this reason.
The purpose of this utility model is to have two flexible members on this sensor for avoiding above-mentioned deficiency that a kind of dual-range force detecting sensor is provided, and one is that the wide range flexible member is measured value energetically, and another is that the journey flexible member is measured small value force in a small amount.
Concrete solution of the present utility model is by shell, flexible member, and the dual-range force detecting sensor that foil gauge is formed, the flexible member of this sensor is made of the flexible member polyphone of two ranges of size, and is gapped between journey flexible member and base in a small amount.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is the structural drawing of dual-range force detecting sensor
This sensor is by pressure head 1, gland 4, and shell 6, base 8, elastic body 5,7, and support chip 3, bolt 2 constitutes.Elastic body 5,7th constitutes an integral body by the flexible member polyphone of two ranges of size, is fixed on the base 8 with bolt 2, and elastic body upper end installation pressure head 1, sealing gasket 10, support chip 3 is enclosed within on the pressure head with gland 4 again, and is threaded with shell 6.The flexible member polyphone of two ranges of size is constituted, and when tested value energetically acted on the flexible member, two flexible members all were subjected to identical load.Wide range flexible member 5 is in normal range of operation at this moment, and journey flexible member 7 needs not to be destroyed under its 10 times of left and right sides of specified range power value effect in a small amount, thereby a disabling mechanism need be arranged in sensor, promptly it no longer deforms when surpassing range certain limit own when journey flexible member in a small amount is stressed, the generation what is called is ended, and this disabling mechanism is to be realized by the gap 9 of 8 of a small amount of journey flexible member 7 and bases.Two flexible members in this sensor adopt the beam type one-piece constructions like this, make handling ease, and paster is convenient.
In the SLC-2 type dual-range force detecting sensor of design, wide range flexible member normal thrust is 10KN, and journey flexible member normal thrust is 500N in a small amount, and range ratio is 20:1.To this sensor test, wherein the non-rectilinear degree lags behind by China National Measuring Science Research Inst., and performance index errors such as nonrepeatability are all less than 0.1%.
Claims (1)
1, a kind of dual-range force detecting sensor comprises shell, flexible member, and foil gauge is characterized in that flexible member is to be contacted by the flexible member of two ranges of size to constitute, and is gapped between journey flexible member and base in a small amount.
