| 摘 要： | 刚柔耦合多体机械系统动力学微分方程组具有刚性和高频振荡的特点，Ｇｅａｒ法通常被认为是求解刚性常微分方程组的经典方法，但当微分方程具有高频振荡的特点时，Ｇｅａｒ法失效，因为它不具备Ａ稳定性区域，隐式Ｒｕｎｇ－Ｋｕｔｔａ方法是具有Ａ稳定性区域的量它带来了巨大的计算量，文中用Ｇｉｌｌ法求解该动力学方程组，效果较理想。

| Abstract: | The dynamical equations of rigid flexible coupling multibody systems have characters of stiffness and high frequency oscillation. The Gear method is usually used to solve equations which have the character of stiffness, but it can not solve equations which have the character of high frequency oscillation. The implicit Runge Kutta method can be provided to solve dynamical equations, but its calculation is quite a task. In this paper, the Gill method is presented to solve the dynamical equations and has a good effect. |
