空间绳网系统展开动力学特性分析

摘要

空间绳网系统是一种新型轻质空间柔性结构，具有很大的应用价值。针对地面环境和太空环境下的不同受力特性，推导空间绳网动力学模型；通过地面试验验证仿真模型的可信度；基于展开面积、飞行距离等性能参数，仿真分析空间绳网展开过程中的绳网位形、应力分布以及能量变化等动力学特性，分析轨道高度、捕获方向和发射参数对展开效果的影响。%Space web system is a new type of lightweight flexible space structure,which indicates great potential application value.Firstly, according to different mechanical environment in space and on the ground,the dynamic model of space web was established.Then,the reliability of the simulation model was validated by the ground test.Finally,based on performance parameters,for instance,deployment area,flight distance, etc,the dynamic characteristics were simulated and analyzed,such as the web shape,stress distribution and energy change,and the influence of the orbit height,capture direction and casting parameters on the deployment process were also analyzed.
