摘要
以栓接结合面为研究对象,对不同预紧力情况下的螺栓联接结构进行试验模态分析,得到该结构的自由模态参数。并对螺栓联接结合面进行几种有限元建模模型分析,对比几种建模方法和试验结果的差距。
The bolted-joint interface is taken as research object in this paper. Various pre-tightening force on bolted-joint structure experimental modal analysis is conducted. Accordingly, the free modal parameters of this structure are obtained.Also, several finite element models are carried out by using different methods. The results of finite element analysis and experimental modal analysis are compared.
