Abstract : With the theory of broad plates and combination method of plate2shell elements with 3D solid elements the finite element , an analysis model of the whole structure of the microaccelerometer is created. The static and dy2 namic properties for the model are analyzed , and the analysis result is presented. Accordingto the condition of strength , the work2beam is optimally designed , which makes analysis for the structure and design of the microacceler2
ometer more rational.
