Dynamics of Multibody Systems with Friction-Affected Sliding Joints

In this paper, a new method for the modeling of planar multibody dynamics with friction-affected sliding joints is presented. Each friction-affected sliding joint is split into two unilateral constraints opposite to each other, and the constraint equality is replaced by unilateral inequalities that are expressed in complementary form. Time-stepping scheme is presented and carried out in an example to analyze its dynamic behavior. The simulation results show that our methods are effective.
