Abstract

The finite element analysis software ANSYS is used for modeling and modal analysis is carried out. The modal analysis is carried out by using block Lanczos method to obtain the mode and natural frequencies of first sixorders. The analysis results show that the sensor model has good low frequency characteristics

and has a certain value in measurement of low frequency. In addition

the results of the modal analysis provide some reference value for the further optimization design of strain acceleration sensor.
