Abstract

In order to study vibration characteristics of a RV reducer, a rigid-flexible coupled dynamic virtual prototype model of a RV-20E reducer was established, and the correctness of the prototype was analyzed with the grey correlation. Then, modal frequencies and modal shapes of the RV reducer are analyzed with the modal analysis. Furthermore, a transient dynamic analysis of the RV reducer was performed using the finite element method. Simulated response signals under different operation conditions were obtained, and compared with acceleration vibration signals of the reducer under different rotating speeds and loads. Simulation analysis results agreed better with those of test investigation. The analysis results showed that load has a less effect on RV reducer’s vibration, while rotating speed obviously affects that.
