| 摘 要： | 应用弹性力学有限元理论,采用有限元分析软件COSMOSWorks对椭圆齿轮进行模态分析,得到了椭圆齿轮的5个低阶固有振动频率和模态振型,并对椭圆齿轮偏心率对固有振动频率和模态振型的影响进行了对比分析.结果表明,偏心率的大小对椭圆齿轮固有频率的大小有较大影响.

| Abstract: | Fifth order natural frequency and modal shape of elliptical gear were obtained from the modal analysis of cosmosworks module in the finite element software. The effect of eccentricity on natural frequency and modal shape of elliptical gear was done a comparative analysis. The results show that eccentricity has a great influence on natural frequency of elliptical gear. |
