为满足载人航天器型号对微重力和真空环境下的维修性仿真验证需求,文章提出并实现了一种混合式仿真验证平台。阐述了在轨维修仿真验证平台整体构架,建立了航天员模型、航天服模型及舱体维修模型,给出了在轨微重力和真空环境下进行维修的可视性、可达性及维修操作时间的仿真验证方法。利用该平台对在轨维修任务进行仿真验证,结果表明,该平台可以有效仿真和验证在轨维修,为维修性设计和优化提供了手段。

Simulation and validation technology of manned spacecraft on-orbit maintenance

According to the simulation requirements of on-orbit maintenance task for manned spacecraft mission, we propose a mixed validation method which can simulate the influence of microgravity and vacuum. Our proposal includes the framework of the simulation system, and the modeling method of the cosmonaut, the extravehicular activity pressure suite, the robot arm model, and others. An actual mission is simulated and the difference between the simulation and the real mission process is analyzed. The results indicate the method is reliable for the maintenance design and optimization.
