摘要
提出了一种基于虚拟样机技术的可展天线展开过程分析仿真方法。利用参数化建模技术建立各零部件的参数化模型;利用有限元分析软件通过模态分析来完成各个零部件的柔性体模型;利用系统动力学分析平台ADAMS将各零部件的模型组装成系统模型;然后将自制的摩擦学行为仿真程序或其他学科行为仿真程序嵌入系统模型中,实现可展天线的虚拟样机建模和展开过程的性能分析与仿真。给出的开发步骤和实例验证了该方法的可行性。
A feasible approach to deployable process analysis and simulation of circular truss deployable antenna was proposed based on the virtual prototype technology. The parameterized modeling technology was applied to build parameterized models for every part, the finite element analysis software was applied to create flexible body models for the parts through modal analysis, and the mechanical system dynamics analysis software platform ADAMS was applied to generate a system model through assembling all models. Then the custom programs such as the tribological behavior simulating program and other discipline behavior simulating programs were embedded in the system model to realize the virtual prototype modeling and the deployable process simulating for the deployable antenna. The presented development steps and examples validated the feasibility of the approach.
