| Abstract: | A reductive method of singular value decomposition is presented in this paper to solve corresponding differential-algebraic equations of motion for constrained dynamic systems. Three sets of reduced equations are developed together with three corresponding methods. It is shown that the SVD reductive method is simple in application and easy to operate by computer, and that the difficulties of numerical integration- resulted from discontinuity of constraints can be overcome. |
