发动机齿轮室盖板有限元模态分析

Modal Analysis of Engine Gear Chamber with FEM

针对发动机齿轮室结构,采用有限元分析方法,分析齿轮室的各谐次模态,给出齿轮室各谐次固有模态频率结果。在此基础上对齿轮室结构进行优化分析,进而改善固有频率,降低整机噪声。

According to the structure of engine gear chamber, finite element method （FEM） was used to analyze various harmonic modes of the gear chamber and get the harmonic inherent frequen- cies. On the basis of this, the structure of engine gear chamber was optimized and analyzed to im- prove the inherent frequency and lower the noise.
