摘　　要：进气系统噪声是汽车的主要噪声源之一,它直接影响着车内噪声和通过噪声,从而影响着驾乘人员的驾乘感受和能否满足通过噪声的法规要求。空气滤清器作为进气系统的关键零部件之一,它不仅仅起到保护发动机的能力,还具备着降低进气系统噪声的能力。空滤的壳体模态直接影响着进气系统的辐射噪声,提高空滤的壳体模态,可以降低噪声,也可以避免空滤壳体的损坏,而影响空滤模态的因素主要为材料的杨氏模量、泊松比和密度,而三个因素是如何影响空滤的模态就需要通过仿真分析进行验证。文章通过Hyper mesh和ABAQUS软件进行空滤壳体模态联合仿真分析,验证各个因素对其的影响。Noise of intake system is one of the main noise souse of vehicle,it affects noise level of driving cab and bass-by noise directly,thus driving feeling and regulation of bass-by noise will be affected.As a main component of vehicle,air filter box not just protects engine,also has ability of noise elimination.Shell mode of air filter box affect radiation noise directly,so increasing shell mode of air filter box not just can reduce radiation noise also can avoid breakdown of air filter box.The factor that affect shell mode of air filter box are Young’s modulus,Poisson’s Ratio and density.Hyper mesh and ABAQUS will be used to simulate shell mode of air filter box and valid how these factors affect shell mode of air filter box.
