| 摘 要： | 对某轿车车身进行了有限元与试验模态分析,计算出各自的振动频率和振型,并基于内积相关度理论,对两者振型相关度进行了计算,结果表明内积相关度不仅能够进行相关性研究,而且能够发现有限元与试验过程中模态的丢失;验证了计算模型的正确,并为进一步的车身设计提供了依据。

| Abstract: | In this paper,the modal analysis of finite element method and experiment on a car-body is performed,and the respective vibration frequences and modal shapes are figured out.Based on the theory of interior cumulation relativity,their mode shapes'relativity is calculated.The results show that interior cumulation relativity can not only be used to research the relativity,but also to find the modal loss during them.The validity of FEM's result is proved,which provides a further grounds for the design improvement of car-body. |
