Abstract  In order to realize the stable rotation of a spacecraft in space with low power consumption, a design method of space large inertia load driving system based on buffer damping was proposed from the perspective of improving its dynamic performance and steady-state performance. Through the matching design of system damping parameter and the use of spring damping technology, the fast starting and stable braking of the driving system in the process of large inertia rotation were realized, the problem of large overshoot of angle stroke was solved, and the requirement of motion accuracy was met. The dynamic modeling of the driving system was carried out by SimulationX software, and the influence of transmission stiffness and damping characteristic on the starting and braking of the driving system was simulated and analyzed. Finally, the experiment verified that the driving system could start and brake large inertia load smoothly, with stable performance and high motion accuracy, which verified the rationality of the design method of the driving system. The research results provide a better implementation method for driving large inertia load with low power.

基于缓冲阻尼的空间大惯量负载驱动系统的研究

为了实现某空间飞行器在空间低功耗平稳转动，从提高其动态性能和稳态性能的角度，提出了基于缓冲阻尼的空间大惯量负载驱动系统的设计方法。通过系统阻尼参数匹配设计，并利用弹簧阻尼技术，实现了驱动系统大惯量转动过程的快速启动和平稳制动，解决了其转角行程过冲较大的问题，满足了运动精度要求。采用SimulationX软件对该驱动系统进行了动力学建模，对传动刚度和阻尼特性对驱动系统启动和制动的影响进行了仿真分析，最终通过实验验证了该驱动系统可以较平稳地启动和制动大惯量负载，且性能稳定，运动精度高，说明了驱动系统设计方法的合理性。研究结果为以小功率驱动大惯量负载提供了一种较好的实现方法。
