| 目的 为了减少芒果包装线上生产事故的发生，解决并联分拣机械手臂承载能力的问题。方法 深入讨论芒果分拣机的并联机构与大小臂结构设计问题。通过SolidWorks simulation有限元分析各关键构件的应力状态，并且定义安全系数图解以评价其结构设计是否合理。结果 大臂所受最大应力为8.056 MPa，其许用应力为75.829 MPa；小臂所受最大应力为31.659 MPa，其许用应力为50 MPa；安全系数图解显示大臂和小臂颜色均为蓝色（蓝色则表示处于安全区域）。结论 构件所受应力远远小于许用应力，并且构件处于安全区域，证明所设计的芒果分拣机械手结构具有可行性。 |

| The work aims to reduce the occurrence of production accidents on mango packaging line and solve the problem of carrying capacity of parallel sorting manipulator. The parallel mechanism of mango sorting machine and the structure design of large and small arms were under in-depth discussion. Through SolidWorks simulation finite element analysis, the stress state of each key component was analyzed, and the safety factor diagram was defined to evaluate whether the structure design was reasonable. The maximum stress of the large arm was 8.056 MPa and its allowable stress was 75.829 MPa. The maximum stress of the forearm was 31.659 MPa and its allowable stress was 50 MPa. The safety factor diagram showed that both large and small arms were blue (the blue color indicated it was in the safe area). The stress of the component is much less than the allowable stress, and the component is in a safe area, which shows that the structure of designed mango sorting manipulator is feasible. |
