| 摘 要： | 基于Virtual.Lab.Acoustics对汽车车身板件对车内噪声的贡献量进行仿真分析,得到车身各板件对车内噪声最大贡献量的峰值频率,用于指导基于阻尼减振降噪技术的汽车改装;并对比汽车左前车门粘贴新型阻尼材料改装前后对车内噪声贡献量,结果表明改装后车门贡献量明显降低。

| Abstract: | The article firstly carried out simulation analysis of the interior noise contribution of car-body panels with Virtual.Lab.Acoustics, to figure out the maximum noise contribution of each panel at peak frequency. The results can be used as application guidance for automobile repacking based on vibration and noise damping technology. Then the interior noise contribution of left front-door with and without treated with the new damping materials were compared, and results indicate the noise contribution of the repacked door decreases obviously. |
