摘要: 研究了航天器相对运动地面动力学实验的构建问题及实验结果的可信性问题。首先利用相似性理论给出了航天器相对运动地面动力学实验的建立方法,而后针对地面实验环境与空间真实环境之间的力学环境差异提出补偿办法,之后针对航天器相对运动地面动力学实验中的干扰因素进行分析并给出相应的补偿策略,然后利用动力学等效性建立航天器相对运动地面动力学实验控制策略,该控制策略中包括力学差异补偿以及实验环境干扰补偿,数值仿真结果与地面实验结果均证明该控制策略能够满足地面实验要求,最后以相似性理论为依托建立相似性度量函数,并利用这一函数证明了航天器相对运动地面实验结果的可信性。仿真结果表明,给出的航天器相对运动地面动力学实验方案可行,其实验结果可信,对地面实验的开展具有重要的参考价值。Abstract: This paper proposes a method to build the spacecraft relative motion's ground-based astrodynamical experiment and figures out an approach to prove the reliability of ground-based experimental results. First, the spacecraft relative motion's ground-based astrodynamical experiment is carried out with the help of similarity theory, then the compensation method for making up the dynamical difference between space environment and experimental environment, after that the dynamical model of experimental disturbances is given for further counteract. Second, an experimental control method similar to space control system is designed for controlling the relative motion and compensating the inertia forces, and both the numerical simulation and experimental results show the effectiveness of control system. Finally, a similarity function used for measuring the similarity degree of experimental result will be helpful in proving the reliability of spacecraft relative motion's ground-based astrodynamical experiment. According to the results of simulation, the experimental scheme is available and reliable. This method is helpful for the development of ground-based astrodynamical experiment.
