Rigid-flexible Coupling Dynamics Simulation of Large Spatial Deployable Thin Membrane Reflector Antenna

膜-梁混合结构的动力学仿真分析是工程应用中一个十分重要、但却极具挑战性的课题，目前国内外还没有十分有效的方法。本文基于能量原理和最小二乘法，发展了一种针对薄膜结构的新型弹簧-质点模型刚度系数求解方法，并将其与通用多体动力学仿真软件ADAMS结合，实现了大型空间可展开薄膜反射面天线刚柔耦合系统的动力学仿真，且准确求解出了薄膜应力。
The dynamic simulation analysis of membrane-beam hybrid structure is a very importantly challenging subject in engineering application. At present, there are some methods which can effectively solve this kind of problems. In this paper, a new method for solving the stiffness coefficient of spring-mass model of thin-membrane structure is developed based on the principle of energy and the least-squares method, and combined with the general multi-body dynamics simulation software ADMAS to realize the dynamic simulation of the rigid-flexible coupling system of the large-scale deployable thin membrane antenna, then the thin-membrane stress is acquired
