摘要: 应用商用有限元分析软件ANSYS 5.5对SIA-120点焊机器人系统作了模态分析.运用分析结果进行模型仿真,验证了所建模型的正确性,同时指出了样机结构设计的薄弱环节.将改进的设计方案应用于模拟样机的仿真模型,用有限元方法定量地计算出了系统改进后的动态特性参数.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.
