Study on Nonlinear Characteristics of Spatial Spreading Mechanism with Multiple Clearance Joints
Based on an improved contact force model with variable stiffness coefficient and Coulomb friction model,the nonlinear characteristics of spatial mechanism with multiple clearance joints are studied.The effects of clearance size,clearance number and gravity on the nonlinear characteristics of mechanical systems are numerically simulated.It is found that the variation of clearance size,the asymmetry of clearance number and the existence of gravity have significant influence on the nonlinear characteristics of the system.The research results have certain theoretical significance for the design of spatial spreading mechanism with multiple clearance joints.
