Study of space large inertia load driving system based on buffer damping

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.
