Numerical Simulation for Non-Smooth Contact Problem in Mechanical Systems

Abstract:

Friction and contact phenomenon widely exist in mechanical systems. In order to tackle the frictional contact problem of mechanical systems, efficient numerical resolution methods and simulation methods are put forward. A mixed nonlinear complementary model describing frictional contact problem is built based on time-stepping method and complementarity theories. In order to solve the model effectively, the block matrix method and linearization method are used to change the mixed nonlinear complementary problem into a linear complementary problem which can be easily solved. At last, the validity of the numerical resolution methods are verified through a numerical example.
