【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.更多还原
