| 摘 要： | 为正确识别太阳电池阵铰链副的刚度参数,用形状简单、建模相对容易的有机玻璃板列阵不同状态下模态试验结果估计待识别参数的初始值,通过线性化目标函数,将参数识别归为易求解的数学规划问题,最终直接用商用有限元分析程序和数学软件实现参数识别。识别结果表明,理论计算值与试验结果基本吻合。

| Abstract: | A method to identify the equivalent stiffness of hinges on solar array by modal shape experiments of organic glass plate which modal was relative simple was presented in this paper.The modal test results under various states were served as the initial values of the parameters that need to identify.The parameter identification was transferred to mathematical programming by linearizing the objective function.Then commercial FEM and mathematical software were used for identification computation.The identification results showed that the theoretical calculation by using this method was similar to the test result. |
