摘 要
近几年随着汽车工业和交通运输事业的迅猛发展,我国汽车保有量逐年增加,但是随之而来的汽车噪声压力日趋严重.同时伴随着人们对汽车依赖性的增加,对乘坐舒适性要求也越来越高.汽车进气系统的噪声占汽车总噪声的30%,而汽车进气系统的振动性能的好坏更是直接影响着车内乘客的乘坐舒适性.所以研究汽车进气系统进行优化设计,对于减少汽车噪声、振动,提高汽车乘坐舒适性具有十分重要的社会意义和应用价值.
本文介绍了汽车NVH特性及其应用,阐述了汽车NVH试验技术的国内外的研究现状及其发展趋势.接着主要以某汽车有限公司的一款问题车型为试验对象,展开车内噪声测试、进气系统噪声识别、模态试验研究等等工作.本文的思路是针对该问题车型,通过实验的方法对其进气系统进行全面的测试,通过实验数据分析与经验的判断,找出主要问题,并且提出有效的问题解决方案.

近几年随着汽车工业和交通运输事业的迅猛发展,我国汽车保有量逐年增加,但是随之而来的汽车噪声压力日趋严重.同时伴随着人们对汽车依赖性的增加,对乘坐舒适性要求也越来越高.汽车进气系统的噪声占汽车总噪声的30%,而汽车进气系统的振动性能的好坏更是直接影响着车内乘客的乘坐舒适性.所以研究汽车进气系统进行优化设计,对于减少汽车噪声、振动,提高汽车乘坐舒适性具有十分重要的社会意义和应用价值.
In recent years, along with the automobile industry and the rapid development of transport and communication, Chinese car retains the quantity increases year by year, but the attendant vehicle noise pressure becomes more and more serious. At the same time, along with the increasing dependence on the automobile, the ride comfort requirements are also getting higher and higher. The automobile air intake system noise accounted for30% total noise of automobile, and the automobile air intake system vibration performance is directly affects the ride comfort of passengers in the car. So the study of the automobile air intake system optimization design to reduce noise, vibration, vehicle, improve vehicle ride comfort has important social significance and application value.
