The micro motion simulation analysis of accelerometer quartz pendulum can get technical method and approach to improve production quality of quartz flexible accelerometer. Starting with the research of physical model of accelerometer quartz pendulum

static calculation and modal analysis on key component quartz pendulum are carried out through the finite element method

visually display stress field and deformation field of the structure of quartz pendulum

and gain natural frequency in different orders and formation. The results indicate that the finite element method can improve the performance of accelerometer.
