Advances in Vibration and Noise Reduction of Hybrid Transmission

Abstract

The vibration and noise problems of hybrid transmission during operation will affect the comfort of HEY. The research on the vibration and noise reduction of hybrid transmission can provide technical support for NVH performance improvement. This paper describes the detection and identification of noise sources, gear modification, optimization of boxes' natural frequency and increasing damping for vibration and noise reduction in hybrid transmission. Finally, the directions of development are analysed for vibration and noise reduction technology of hybrid transmission.
