In order to analyze and improve the robotic welding dynamic performance for small and medium-sized vertical arc weld operation,the combined simulation of robotic dynamics is carried out based on MATLAB and Adams.Firstly,the system composition of small and medium-sized arc welding robot is briefly introduced.Secondly,the dynamic equation of welding robot is established according to Newton Euler equation,and the correctness of the model is verified by Adams.Then,the virtual prototype model of welding robot is established in Adams,and the virtual prototype model is combined with the MATLAB control system model through the Controls interface module.Finally,for the typical small and medium-sized vertical arc weld,the combined simulation of robotic dynamics is carried out to analyze the dynamic characteristics of robotic motion,so as to provide a theoretical basis for robotic trajectory planning and dynamic performance improvement.
