Failure Analysis of Planetary Gear Shaft of Power Split Device Based on Multi-Body Dynamics

Abstract:

Power split device (PSD) affects the power performance and control strategy of hybrid electric vehicle (HEV). In this paper, a new threshold function for wavelet denoising is used to reduce noise in test torque and rotational speed data. The dynamic simulation is carried out at the moment of planetary gear shaft (PGS) failure, after the rigid-flexible coupled model of PSD is established. According to the obtained stress of PGS, analysis of PGS fracture is verified.
