Modeling and simulation for wear prediction in planar mechanical systems with multiple clearance joints

The main goal of this work is to develop a comprehensive methodology for predicting wear in planar mechanical systems with multiple clearance joints and investigating the interaction between joint clearance, driving condition, wear. In process, an effective contact surface discretization method together Lagrangian are used establish dynamic equation multibody system. Considering change surface, improved nonlinear force model suitable complicated conditions utilized evaluate intrajoint forces, friction effects interconnecting bodies discussed using LuGre model. Next, forces developed integrated into Archard compute depth caused by relative sliding geometry bearing updated. Then, crank slider mechanism employed perform numerical simulations order demonstrate efficiency procedures adopted throughout work. correctness proposed verified comparing other literature simulation results. results show that sensitive different initial conditions, evolving boundary makes dynamics system prediction more complex. This study helpful optimizing mechanism’s design.
