摘要
汽车的NVH性能是汽车的重要性能之一,影响汽车NVH性能的因素很多。本文通过对汽车的NVH试验,发现一些常见的由动力总成系统、传动系统及进排气系统等引起的车内振动噪声问题,在理论上分析了产生这些问题的主要原因并对问题车辆以尽可能短的时间,小改动、低费用地改进,以达到车辆设计的NVH性能要求。解决问题的方法和思路对从事汽车NVH工作的人员有一定的指导意义。
The performance of powertrain mounting system,transmission system and exhausting system can have impact on vehicle NVH characteristics significantly.Based on experimental data,this paper analyzed some vehicle NVH problems caused by aforementioned subsystems analytically.In order to meet requirement of vehicle NVH performance efficiently,we also illustrated some basic solution method for these problems.The test results and solution method of presented vehicle NVH problems in this paper are applicable for measurement and design of vehicle NVH characteristics.
