Dongping Jin, Xiaoyu Wang, Hao Wen
Abstract: The paper reveals the quasi-periodic characteristics of a tethered sub-satellite with attitude by numerical approach and ground-based experiment. The dimensionless ordinary differential equations that govern the dynamics of the tethered satellite system are obtained according to Kane’s method first. Numerical simulations show that there exist a quasi-periodic motion and its co-existence in the system. To verify the quasi-periodic motion, afterwards, a test on the quasi-periodic motion is made via a ground-based experimental platform, which is featured by using a combination of air-bearing facilities and on-simulator thrusters to achieve the physical simulation of the gravity gradient field and Coriolis force of tethered satellite on orbit. The experiment results indicate the existence of quasi-periodic motion.
