摘　　要：建立作业臂的ADMAS虚拟样机模型,对工作臂进行动力学仿真,得到其动态特性曲线,由仿真结果可知工作臂运行过程较平稳。同时在两种危险工况下进行整机的有限元分析,得到应力分布和应变分布,并根据应力最大位置处的受力曲线,以最大载荷分别对中臂和下臂进行加载,进行静力分析,结果表明最大应力点受最大载荷时仍然满足设计要求。The virtual prototype model of ADMAS is established,and the dynamic simulation is performed,the dynamic characteristic curve is obtained.The simulation results show that the operating process of the working arm is relatively stable.At the same time,the finite element analysis is carried out under two kinds of dangerous conditions,the stress distribution and strain distribution are obtained.According to the stress curve of the maximum stress position,the maximum load is used to load the middle arm and the lower arm respectively,static analysis is made.The results show that the maximum should still meet the requirements by the maximum load point,which provides a reference for optimizing the design of aerial vehicles.
