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.
