摘　　要：为全面准确地评价六轴工业机器人的位姿准确度和位姿重复性等性能指标,指导机器人不同工况下的应用,对机器人的多工作域性能指标进行测试分析。利用DH方法建立某型机器人运动学模型,通过蒙特卡洛方法求解该型工业机器人的最大工作空间;对机器人最大工作立方体进行区域划分,得到机器人多工作域;利用激光跟踪仪完成机器人多工作域性能测试。结果表明:该型机器人位置准确度为3.305 mm,位置重复性为0.039 mm;分析多工作域性能可知,位于机器人工作空间上部的工作域位置准确度优于下方工作域;机器人各工作域的位置重复性基本一致,内侧工作域位置重复性略优于外侧工作域。To evaluate the pose accuracy and pose repeatability of the six-axis industrial robot comprehensively and exactly,and guide the application of the robot under different working conditions,multi-working zone performance of six-axis industrial robot was tested and analyzed.The kinematics model was established by using DH(Denavit Hartenberg)model,and then the maximum working space of this industrial robot was solved by Monte Carlo method.To get the multi-working zone of the robot,the maximum working cube was divided,and then the pose accuracy and pose repeatability of multi-working zone was tested by using the laser tracker.The results show that the positioning accuracy of the robot is 3.305 mm,and the positioning repeatability is 0.039 mm.Positioning accuracy of the upper working zone is better than that of lower working zone.Positioning repeatability of the whole working zone is little difference,positioning repeatability of inner side is slightly better than that of outside.
