Dynamic Behaviour Analysis of Single Stage Planetary Gearbox Under Non-Stationary Operations Using Experimental Test Rig

摘要

Planetary gearboxes are mostly used in very hard working situations such as helicopters, wind turbines, heavy trucks, marine vehicle, hybrid cars etc. In order to understand the basic nature of planetary gearbox vibration, this paper includes a vibration and dynamic behavior of single stage planetary gearbox using test rig. Comparison the fault diagnosis of normal planet gear and damaged planet gear, we also calculate the mesh and characteristics frequencies at different operating speed. Based on this assumption, Numerical simulation and vibration signal model of planetary gearbox is obtained. Experimental study is used to verify the model.
