When the traditional methods are used to analyze the dynamics of the robot arm structure, the stability of the arm structure is not good and the simulation effect of the operation process is not good. For this reason, Kane method is introduced in this paper to carry out dynamic simulation analysis of industrial robot arm structure. The operating process of the industrial robot arm structure was simulated by Kane method, and the angular acceleration of the robot’s main arm, forearm and push rod was solved in each cycle. The Jacobian matrix of the 5 degree of freedom manipulator joint is established, the singular configuration of each joint is calculated, and multiple joint variable combinations are generated by random number. The forward motion equation of the robot endpoint set was solved to obtain the endpoint set of the robot. The Lagrangian method was used to model the robot with Kane 3D simulation software to simulate and analyze the dynamic process of the driving torque required to grab the mass workpiece at the three joints. The joint motion model of robot is established on ADAMS simulation software, and the torque curve of the rotating joint of industrial robot arm structure is obtained. MATLAB simulation software is used for simulation. The results show that the integrated design method of manipulator and machine tool is correct, which provides a comprehensive data basis for the selection of servo motor.
