Abstract

The ambient random vibration is one of the important factors affecting the flight safety and reliability of quadrotor unmanned aerial vehicles (UAVs). Therefore the vibration stress analysis of quadrotor UAVs with general structures is helpful to the structural design and optimization. According to vonMises Criterion, the stress analysis of main composite/metal mixed structures was carried out and according to Tsai-Wu Criterion, failure analysis of main composite structures was conducted. The numerical simulation results show that the main structures of the fuselage can meet the strength requirement; the arm is made of composite material by one-piece forming process, and the stress level of the arm pole is higher than that of the motor base; there is failure of composite material only near the hole of the arm riveted to the embracing ring. By optimizing the layering of the arm, it can reach the strength target of no arm failure under ambient random vibration with the weight reduced by 4.5%.
