A New Method for Solving the Constraint Multibody System Dynamic Equation
Aiming at the problem of solving the constraint multibody system dynamic equation, a new method is proposed. This method takes the function of general coordinates to replace the second derivative of the general coordinates in the dynamic equation according to Taylor formula, and considers the converted dynamic equation and system constraint equation as a system of non-linear equations to find the solution by Newton method. Experimental results show that the proposed method is efficient and accurate for solving the constraint multibody system dynamic equation.
