摘　　要：为了提高箱体零件机械加工的打磨精度,研究利用动力学分析设计了具有多自由度的打磨机械臂,并利用模糊控制理论对机械臂进行柔顺控制。最终,利用有限元技术对所设计的打磨机械臂进行了验证。结果表明,机械臂在X、Y、Z方向上的最大误差分别为0.39mm、0.35mm和0.32mm,各方向的最大轨迹误差均控制在0.5mm以内,达到了铸造行业对工业零件毛刺打磨的精度标准。In order to improve the grinding accuracy of box parts machining,the study designed a grinding robot arm with multiple degrees of freedom using kinetic analysis,and used fuzzy control theory to control the robot arm sofly.Finally,the designed grinding robotic arm was verified using finite element technique.The results show that the maximum errors of the robotic arm in the X,Y,and Z directions are 0.39 mm,0.35 mm,and 0.32 mm,respectively,and the maximum trajectory errors in each direction are controlled within 0.5 mm,which meets the casting industry's accuracy standards for burr grinding of industrial parts.
