Dynamic Simulation and Fault Diagnosis of Planetary Gear Systems
摘要
Abstract
Nowadays planetary gearboxes have been widely used in military and civilian equipment. Study on fault diagnosis of planetary gearboxes is of important significance. In this paper, a dynamic model of the planetary gear transmission is built to study its fault mechanism and characteristics. The influence of the crack on the meshing stiffness is analyzed. The fault characteristic frequencies are studied under the three conditions, namely normal gear, cracked solar gear and cracked planet gear. Finally, the crack fault experiment is carried out on a test rig, and the results are employed to verify the correctness and effectiveness of the fault detection simulation. The provided feature frequencies can be applied to the fault diagnoses of planetary gear systems.关键词
