| Abstract: | ? Based on the idea of the optimal control, the method of DAEs for multibody system dynamics is discussed. The best Baumgarte's correction parameters which reduce the constraint errors to the machine precision are obtained. A high precision, efficiency and stability self correction algorithm of constraint errors for nonlinear system dynamics is presented. The effectiveness of the present method is demonstrated by numerical example. |
