【摘要】 在地面进行空间对接动力学的模拟实验是实现空间对接不可或缺的过程。利用Stewart平台实现由动力学方程解算得到的两航天器相对运动轨迹,提出用质量-弹簧-阻尼系统来研究空间两航天器对接动力学过程模拟中的稳定性问题。建立了基于Stewart平台位置内环的动力学回路系统模型,推导出为使模拟系统稳定的动力学参数之间的配置关系,推证了Stewart平台的频率特性与动力学系统谐振频率之间的关系。为空间对接动力学过程的模拟奠定了理论基础。更多还原

【Abstract】 It is an indispensable process to simulate space docking dynamics on the ground. Relative movement trajectory is the solution of dynamics equation, and can be realized by Stewart platform. It is put forward to research stable problem in the process of simulating docking dynamics of two spacecrafts by mass-spring-damp system. Built is model of dynamics loop system based on position inner loop of Stewart platform, deduced is the configuration relation of dynamics parameters assuring system stability, and the relation between frequency characteristics of Stewart platform and resonant frequency of dynamics system. It has laid theory foundation for simulating space docking dynamics process.更多还原
