三环减速器的剧烈振动问题是制约三环减速器推广使用的主要原因,其中的振动有很大一部分来源于内齿板。运用ANSYS软件,建立了三环减速器内齿板的参数化模型,介绍了ANSYS的模态分析方法并对内齿板进行了模态分析,获得了内齿板固有频率及振型特征,为进一步研究三环减速器的振动问题提供理论参考。 Tricyclic reducer vibration problem is to restrict the promotion of the use of three-ring reducer the main reason for which a large part of the vibration from the internal tooth plate. Using ANSYS software, the parametric model of internal tooth plate of three-ring reducer is established. The modal analysis method of ANSYS is introduced and the internal tooth plate is modeled. The natural frequency and mode shape of internal tooth plate are obtained. Further research on the vibration problem of tricyclic reducer provides a theoretical reference.
