According to the working principle of a certain type of high- altitude vehicle, the force analysis of working arm of the high-altitude vehicle was carried out. Based on this,the working conditions of lifting, lowering, rotating, and luffing were simulated to consider the influence of the angle variation of luffing angle ï¡ and folding angle ï¢ on the stress of the working arm. Using MATLAB to draw the diagrams of the dynamic relationship between the stress and the amplitude luffing angle ï¡ and folding angle ï¢ , which provides a theoretical basis for the optimal design and life prediction of the working arm of a high-altitude vehicle.
