| 摘 要： | 建立了某运动休闲车(SRV)白车身的有限元模型并进行了模态分析,得到了SRV白车身的固有频率和振型。模态试验和仿真计算的对比分析结果表明,所建立的白车身有限元模型较好地反映了原结构的振动特性。根据模态分析结果,提出了改善该SRV车型NVH性能的改进措施。 |

| Abstract: | The finite element model of body-in-white of a SRV is established.The implicit frequency and vibration types are obtained by modal analysis.The contrastive analysis of modal test and simulation computation show that the finite element model of body-in-white has well represented the vibration characteristics of the original structure.According to the result of modal test,some measure is brought forward in order to improve the NVH of SRV. |
