Abstract
In the light of the property of piezoelectric accelerometer in engineering application,the mathematic model base on mechanics model is established.The effect of substrate,piezoelectric slice,seismic mass on the natural frequency of compressed piezoelectric accelerometer is anlyzed,some influencing factors and its rule is found through calculating and simulating.The results of computation and simulation indicate the effectiveness of the calculating method.
