摘要
新车型的设计研发过程中应首先考虑的是白车身的动态特性,通过试验得到的动态特性参数能很大程度的改变现有新车型开发周期长、成本高的现状,从而可以尽快的发布以及上市新车型。通过试验方法对某一款汽车的两种白车身模态进行了分析对比,得到其各项模态性能参数,通过对结果的分析为以后进一步研究白车身NVH性能提供了试验依据。
Dynamic characteristic should be first considered in the process of design research and development for body-inwhite,dynamic characteristic parameters obtained by test can greatly change the long cycle of new model development,the present situation of the high cost,which can release as well as the listing of new models as soon as possible. In this paper,two test methods for a body-in-white mode are analyzed and compared,the modal performance parameters are got,analysis of the results can provide experimental evidences for the further research NVH performance of body-in-white.
