| Abstract: | In this paper,the FEM(Finite Element Analysis) was used to study the structural strength and the vibration modal of a certain accelerometer.Through the structural static analysis,the overall stress situations were obtained.Through the structure modal analysis,the natural frequency and the modal shape of the structure were obtained.The results of the analysis of this paper provide a base for structural design and improvement of the accelerometer. |
