Analysis of friction effects on satellite antenna driving mechanism with clearance joints

The existence of clearance in joints of mechanism is inevitable. In this paper, the friction effects in clearance joints on dynamic responses of driving mechanism of satellite antenna are studied. Considering clearances in joints, the contact force model in clearance joints is established using a nonlinear continuous contact force model and the friction effect is considered by using a modified Coulomb friction model. Then the dual-axis driving mechanism of satellite antenna with clearance joints is used as the application example. The numerical simulation of dual-axis driving mechanism with clearance joints is presented. The friction effects of clearance joint on dynamic responses of the dual-axis driving mechanism are discussed and analyzed quantitatively for four cases with different friction coefficients. The investigation results show that the increase of friction coefficient will decrease the vibration amplitude of the driving mechanism system.
