基于ANSYS的MEMS器件中偏心齿轮模态分析

Model Anlysis of Eccentric Gear in MEMS Based on ANSYS

模态分析可以确定一个结构的固有频率和振型。固有频率和振型是承受动态载荷结构设计中的主要参数。共振是机械结构不可避免的问题之一,利用大型有限元分析软件ANSYS对设计的MEMS保险机构中偏心齿轮结构进行模态分析,有效预估了结构的振动特性,优化了结构设计。

Model analysis can calculate natural frequency and vibration type of a part. Sympathetic vibration is one of important problem in structure design. Designed eccentric gear delay mechanism structure can be model analysis using Finite element analysis codes ANSYS, and the results will effectively estimate vibration specific of structure in order to optimize structure design.
