摘要
连接刚度对结构的固有特性有很大的影响,在对接面附近刚度损失可达到30%—40%,因此对此类问题进行研究具有很重要的工程意义。本文针对导弹结构,给出了考虑连接刚度计算结构固有特性的方法。并通过算例进行理论计算结果与试验结果的比较,表明这种方法具有一定的实用价值,给结构设计提出了指导性结论。
The joint stiffness has an effect upon the structure inherent property.Stiffness has thirty to forty percent loss near joints.So research on this problem is helpful to the engineering.This paper presented the method of normal modes analysis of one missile considering the joint stiffness.Compare the theory values and examination values,it showed that this method was useful and proposed some instructive conclusions.
