N2 - In this study, an improved contact model in revolute joint with clearance is establishedby considering the axial dimension of the joint, energy dissipation and the nonlinear power exponent from material.The friction effectisdescribed using the modified Coulomb friction model.Then simulationis carried out to investigate the influence of clearance size, input driving torque, and friction coefficienton impact dynamics of development for solar panel with cylindrical clearance joint. The results show that the effect of the clearance size, input driving torque and friction coefficient on angular displacement is slight, but obvious on angular velocity, and extraordinarily obvious on the joint reaction force, which may effects the accuracy and dynamic stabilityof the system, even induce the dynamic behavior of system tends to be nonlinear.
