某混动车型怠速充电时方向盘振动问题分析与对策研究

Analysis and Countermeasures of Steering Wheel Vibration Problem when Idle Charging of a Hybrid Model

NVH性能在混合动力汽车开发过程应重点验证与优化。公司某混动车型在开发阶段发现怠速充电时方向盘振动大问题。为解决此问题,从振动产生与传递的工作原理出发,分析并制定出可行的改进方案,同时结合项目开发时间与经济成本要求,最终选定最优方案、解决该问题,新产品NVH性能有效提升。

NVH performance should be validated and optimized during the development of hybrid electric vehicles.In the development stage of a hybrid model of the company,the steering wheel vibration was found to be a big problem during idle charging.In order to solve this problem,based on the working principle of vibration generation and transmission,the feasible improvement scheme is analyzed and formulated.At the same time,the project development time and economic cost requirements are combined,and the optimal scheme is fi nally selected to solve this problem.The NVH performance of the new product is eff ectively improved.
