The dynamic mathematical model of the crank-slider mechanism was established by using Lagrange equation, and the coupling between the elastic motion of the connecting rod and the rigid body of the mechanism and the viscous friction of the moving pair were considered in the modeling process. A numerical simulation was performed on an example. The results It shows that the elasticity of the connecting rod and the viscous friction of the moving pair have a certain influence on the movement of the mechanism
