| 摘 要： | 利用Ｌａｇｒａｎｇｅ方程建立了典柄滑块机构的动力学数学模型，在建模过程中考虑了连杆的弹性运动与机构刚体运动的耦合以及运动副的粘性摩擦，对一个算例进行了数值仿真，结果表明：连杆的弹性和运动副的粘性摩擦对机的运动都具有一定的影响。

| Abstract: | Lagrange equation is applied to develop dynamic equations for the slider crank mechanism with elastic connecting rod. Viscous friction and coupling effect are considered between rigid body motion and elastic deformation of connecting rod. The analog computation of a sample shows that both of the aforementioned effects can affect the motion of the mechanism. |
