| Abstract: | To optimize structure design of spot welding robot, model analysis was performed on SIA 120 spot welding robot with ANSYS software by finite element method. Using the results of the model analysis, a proposed model was simulated and proven to be accurate by the simulation outcome. The imperfection of structure design of the robot was pointed out. With models in which improved design scenario was employed, parameters of dynamic properties of the ameliorative system were carried out quantificationally with ANSYS 5.5, which can provide a criterion for structural dynamic modification or design of similar robot. |
