The structure of symmetric cantilever beam and mass has been chosen. Its static characteristics and dynamic characteristics are summarized. The models of cantilever deformation and its dynamic response are established. The sensitivity and basic resonant frequency of the micro-accelerometer as functions of beam thickness and beam length are analyzed ,and the geometrical parameters are optimized. Finally, the micro-accelerometer working in the virtual environment proved the result of virtual design.
