运用Hamilton原理建立了空间绳系展开动力学模型,研究绳系展开过程中绕线盘出线、系绳振动以及末端质量的运动规律,并利用中心差分法、四阶Runge-Kutta和预估校正法等数值方法对绳系的自由展开过程进行仿真,仿真结果显示该模型可以较精确描述绳系系统在展开过程中的复杂非线性动力学行为,绳系自由展开不能满足稳定展开的要求,仿真数据可以为后续的绳系展开控制提供参考依据.%A dynamic model of space tether deployment was established using Hamilton' s principle to study motion laws of drum releasing tether, tether vibration and end-mass moving during tether deployment. Numerical simulation for free tether deployment was calculated using central difference method, four-order Runge-Kutta method and predictorcorrector method and so on. The simulation results showed that the model can accurately describe the complex nonlinear dynamic behavior of a space tether system during deployment; free deployment cannot meet requirements of stable tether deployment, but the simulation data provide a foundation for tether deployment control further.
