Study on impact dynamics of development for solar panel with cylindrical clearance joint
In this study,an improved contact model in revolute joint with clearance is established by considering the axial dimension of the joint,energy dissipation and the nonlinear power exponent from material.The friction effect is described using the modified Coulomb friction model.Then simulation is carried out to investigate the influence of clearance size,input driving torque,and friction coefficient on 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 stability of the system,even induce the dynamic behavior of system tends to be nonlinear.
