【Abstract】 Based on the Gauss’ s principle of least constraint the optimization method in modeling of dynamics is described in this paper. Comparing with the traditional method of finding solutions of differential equations, the optimization method has special advantages in modeling of dynamics of multibody systems with complicated constraint conditions. A net system connected by thin elastic rods is taken as an example to examine the process of modeling.更多还原
