大疆F450四旋翼无人机的坠落碰撞仿真分析与结构安全评估OA

The DJI F450 quadcopter unmanned aerial vehicle(UAV)is widely utilized across various fields owing to its advantages such as excellent maneuverability and simple structure.To address issues related to the structural strength and safe flight of the DJI F450 UAV,a finite element model was established using ANSYS Workbench for simulation analysis.The study simulated the impact of the UAV on the ground under different failure conditions,considering variations in altitude and weight during a crash.By comparing the maximum equivalent stress of the drone impacting the ground under different conditions,it was determined that the DJI F450 drone can operate at a flight height of 5 m and a flight weight of 1.6 kg while ensuring structural safety.It is concluded that these results can provide a theoretical basis for the next step in the structural optimization design of the drone.
