摘要: 目前在车身设计领域，车身多采用承载式设计，几乎承担了所有的扭转和弯曲载荷，车身的模态会直接影响汽车车身对的各项关键指标，如车身NVH性能等。因此，研究车身区域结构胶应用对车身模态的影响并进行车身试验测试，对提高白车身各项性能具有重要的意义。本文首先对白车身模态进行试验，再对车身典型区域进行选取并涂胶，最后进行模态测试。通过对比三种方案，研究胶接工艺对白车身各阶模态的影响。
Abstract: In the field of body design, the body mainly adopts integral design, which takes almost all of torsion and bending load. Meanwhile, the body mode can influence directly some key indicators of car body, such as NVH performance and so on. Therefore, it is significant for improving the performance of the white body to study the application of structural adhesive and the effect of structural adhesive on body mode. This paper first took a modal test on the white body. Then, a modal test on the white body after gelatinizing the typical areas of body was taken. Finally, the influence of body modes was explored by comparing the three kinds of glue solution.
