Research on Transverse Sensitivity Property of Cymbal Piezoelectric Vibration Acceleration Sensor
For the problem of higher transverse sensitivity ratio of the cymbal piezoelectric vibration acceleration sensors, a mathematical model of output voltage sensitivity is established which employ orthogonal and array methods to reduce the transverse sensitivity ratio of the piezoelectric vibration acceleration sensor. Two compensation methods are designed. The results showed that the array and orthogonal methods can decrease the effect of the transverse interference of acceleration sensor effectively and control the relative error in a smaller range, improve the measurement accuracy of the sensors.
