Nonlinear Dynamics Response of a Planar Mechanism with Two Driving Links and Prismatic Pair Clearance

الملخص EN

The influence of the joint clearance on the dynamic response of a planar mechanism with two driving links and prismatic pair clearance is investigated under variable input speeds of the system.

The simulation model was built with a nonlinear impact model.

The normal contact force is characterized by Hertz contact theory and an energy dissipation term.

A tangential friction force is involved in the simulation model based on Coulomb’s friction law.

The simulation results indicate that the largest Lyapunov exponents are dependent on the clearance size and the input speed.
