Abstract:
The differential algebraic equation,the dynamic which of multibody system,is a system of index three.It is a very difficult problem for solving.At present ,there are no satisfactory numerical methods yet.The symplectic partitioned Runger Kutta methods of the differential algebraic equations are new numerical methods presented in recent years,and the authors use it mainly for simulation in the canonical form of the equations.
