| 摘 要： | 对广泛应用的Lagrange方程的动力学本质做了探讨,指出在引入速度变换矩阵后,Lagrange方程实际上是牛顿第二定律的一种表示方式;由于引入了速度变换矩阵,Lagrange方程可以方便地在任意的坐标系中建立,对动力学问题的求解提供了一个途径。

| Abstract: | In this paper the essence of dynamic mechanics for Lagrange equation is discussed. It is indicated that after a speed's transform matrix, the Lagrange equation is an expressinon form of the second Newton's law. Because the transform matrix of a speed is introduced, the Lagrange equation may be set up expediently. This method provides a way for solving the problem of dynamic mechanics. |
