摘要

为了对RV减速器系统进行共振响应分析，首先要确定RV减速器系统的固有频率。以RV-320E减速器为研究对象，考虑曲柄轴和摆线轮公转运动的切向自由度，采用集中质量法，建立了16自由度的RV减速器动力学模型。通过牛顿第二定律、定轴转动微分方程，建立了系统动力学微分方程，计算出系统的固有频率。分析了零件材料属性对1阶固有频率的影响，画出了影响曲线图。

Abstract

In order to analyze the resonance response of RV gear reducer system，the natural frequency of RV gear reducer system should be determined first. Taking RV-320E gear reducer as the research object and considering tangential degrees of freedom of crank shaft and cycloid wheel rotation motion，the 16 degrees of freedom dynamic model of RV gear reducer is established by centralized mass method. The dynamics differential equation of the system is established by Newton's second law and the differential equation of fixed axis rotation，and the natural frequency of the system is calculated. The influence of the material properties of the parts on the first-order natural frequency is analyzed and the influence graph is drawn.
