摘要
为提高农业无人机的飞行稳定性,本文先对无人机整体结构进行设计,并通过初始优化和谐响应优化后,得到机架增加的肋条厚度应优化为4.41 mm,支臂直径为30.1 mm,X轴最大位移为1.437 mm,相比降幅为15.5%。最后,经田间飞行试验发现,无人机滚转角、俯仰角和偏航角基本稳定在0°左右,角度变化在±10°之间,且不受碰撞影响,还能够有效获取大面积作物的图像信息。该研究可为农业无人机机架结构改进提供一定理论基础。
To improve the flight stability of agricultural unmanned aerial vehicles(UAVs),this study first conducted the overall structural design of the UAV.After initial optimization and harmonic response optimization,the results showed that the thickness of the added ribs on the UAV frame should be optimized to 4.41 mm,the arm diameter to 30.1 mm,and the maximum displacement along the X-axis to 1.437 mm—representing a reduction of 15.5%compared with the pre-optimization state.Finally,through field flight tests,it was found that the UAV’s roll angle,pitch angle,and yaw angle were basically stable around 0°,with angle variations within±10°.Furthermore,the UAV remained stable even under collision conditions and could effectively capture image information of large-area crops.This study can provide a certain theoretical basis for the structural improvement of agricultural UAV frames.
