摘要
采用"质点-杆"模型建立空间绳系系统模型,考虑飞行器、控制机构和绳系的质量,研究绳系系统由释放到稳定状态的受力特性,在此基础上利用两阶段方法对绳系系统的展开过程进行仿真;此模型对展开过程中动力刚化的考虑使其可以较准确描述绳系系统空间展开的动力学过程,为以后绳系展开等空间技术提供了参考依据。
Considered the quality of the aircraft, control mechanism and the tethered, a model of space tethered system was established in this paper. At first, the mechanic characteristics from release to the steady state were analyzed. Then, the deployment of a space tethered system was simulation based on two-stage method. As the dynamic toughened phenomenon in the deployment was considered, the dynamic process description of the space tethered system deployment was more accurate, and it provided a reference for the later space technology about the tethered system deployment.
