摘要
本文介绍了导弹天线罩地面模拟试验的技术与方法 ,并采用有限元素法求解某型号天线罩结构在热流与机械载荷的作用下 ,结构内部随时间变化的温度场及应力场。计算时主要是依据模拟试验中所施加的边界条件和载荷条件进行的。
Thermal problem of structure has critical effect on the performance of missile and is being studied heavily .As the flight environment of the aircraft is very complicate,it is essential to calculate and analyze the thermal test. In this paper,using structure thermal test method,the antenna cover was studied and the temperature and strain of the critical points were measured.Using the finite element method,the temperature and strain field,which changed with time in the structure,was calculated while the antenna cover was suffering high temperature thermal shock,heat flow and mechanical loading.
