| Abstract: | Based on the body modal test,natural frequencies and mode shapes of two types of body with / without windscreens are obtained.The two types of body finite element models are established,and modified models are also founded.Research shows that the application of integrated analysis techniques can better solve the structural changes brought about by the body of the dynamic characteristics change.In this paper,auto-body integrated analysis / test and evaluation strategies are introduced,and a preliminary basis for the design and analysis of auto-body dynamics is established. |
