某轻型车变速器后悬置支架模态分析及优化

The Modal Analysis And Optimization Of Rear Mount Bracket For a Light Vehicle Transmission

在某轻型车的动力升级过程中,需更改变速器后悬置支架结构,因此要对此结构进行仿真分析。文章首先根据数模搭建CAE分析模型,然后进行此结构件的模态分析,最后根据仿真结果进行优化设计。通过实验验证,最终优化后的结构满足模态设计要求,使整车的振动噪声性能得到了提升。

In the process of power upgrade of a light vehicle, it is necessary to change the rear mount bracket structure of the transmission, so the structure is simulated and analyzed. First, the CAE analysis model was built according to the mathematical model, then the modal analysis of the structural parts was carried out, and the optimization design was carried out according to the simulation results. Through experimental verification, the optimized structure meets the modal design requirements, and the vibration noise performance of the vehicle is improved.
