Free Vibration and Sensitivity Analysis of RV Reducer

摘要

This work develops a dynamic model to investigate free vibration characteristics of RV reducer. The dynamic model considers key factors affecting vibration such as involute and cycloid gear mesh stiffness, crankshaft bending stiffness and bearing stiffness. For the model, equation of motion is derived. Numerical results of the associated eigenvalue problem reveal that the vibration modes are classified into three types: rotational, translational, and planetary component modes. Furthermore, sensitivity of natural frequencies associated with three vibration modes to stiffness and inertia parameters are studied. The investigation of the work is helpful for understanding the relationship between parameters and vibration modes.
