变速箱NVH问题的分析及优化

Analysis and optimization for the gearbox NVH problem

对变速箱NVH问题进行了分析,着重对变速箱敲击噪声的产生机理、传递路径等方面进行了阐述。从加大飞轮转动惯量、调整离合器预减振、加强变速箱的壳体刚度三方面进行了优化,解决了变速箱的敲击问题。

It analyzes the gearbox NVH problem, emphatically expounds the mechanism of the gearbox percussive noise production, the transmission path, etc., carries out the optimization from three aspects of increasing the moment of inertia of the flywheel, adjusting the pre-vibration of the clutch and strengthening the shell stiffness of the gearbox, and solves the gearbox impact problem.
