【 摘 要 】

To reveal the kinematic and dynamic characteristics of the main motion system of reciprocating machine tools, the paper adopts vector equation method to set up motion mathematical models for the main motion system, carries on the kinematics simulation analysis by using MATLAB Simulink, and get these kinematic characteristic curves. The force analysis of the components in the main motion system is carried out on the basis of motion analysis. First, force analysis of the components in the main motion system; Second, the dynamic calculation matrix is obtained by the assembly of the equilibrium equations of the mechanics. Finally, the analytical solutions of the main motion system dynamics and the dynamic characteristic curves of the main motion system of the machine tool is obtained by using Simulink. All the calculated data will be the data foundation for fatigue life prediction of reciprocating machine tools in the future.
