一种框架面板式空间结构的建模、分析与试验研究

Model Designing, Simulation and Test for Frame-board Space Structure

针对一种框架面板式空间结构,建立了结构有限元模型,重点考虑了连接、接触、局部刚度、材料模型等问题,利用该模型对结构进行了动力学特性和动力学响应分析。随后进行了结构力学试验,并对比分析了理论与试验结果,两者吻合较好,说明本设计分析方法和对关键环节的处理在工程上是可行的。

According to the frame-board space structure, a finite element method （FEM） model was made, in which the link, contact, local stiffness and material model were taken into account. Using the FEM model, the mode analysis and frequency response were done. After dynamic test, the analysis and test results were compared and they were in good agreement with each other, which shows that the modeling method and key component processing method are feasible in engineering application.
