Research of Piezoelectric Multidimension Force Sensor
Aiming at the problems of traditional piezoelectric dynamometer such as limited effective testing area,inconsistent output results at different test positions and tedious torque value acquisition,a multi-dimensional force sensor based on regular oc-tagonal chip was proposed based on sensor layout and the characteristics of quartz chip cutting.On the basis of theoretical analy-sis,the design rationality of regular octagon chip was verified by calculation and simulation.The calibration experiments of the de-veloped multi-dimension force sensor were carried out.The calibration results show that the sensors have high tangential sensitivi-ty,good anisotropic linearity and repeatability,little interdirectional interference and good test performance.
