无人机起落架地形自适应系统设计

近年来随着无人机市场的发展,多旋翼无人机以优良的操控性能和可垂直起降的方便性等优点迅速获得了广大消费群体的关注。但是现有旋翼无人机起落架对地形要求略为严苛,在特殊地形降落时,无人机往往因为地面的不平坦发生侧翻等问题,严重时可能造成巨大的经济损失。文章在传统无人机起落架设计方案的基础上,根据地形自适应场景要求,对起落架减振弹簧和自由伸缩机构提出了设计更改。并通过关键参数的分析,验证了其工程可行性和地形自适应方面的改善作用。

Abstract： In recent years, with the development of the UAV market, the multi-rotor UAV has attracted the attention of the con- sumers for its excellent control performance and the convenience of vertical take-off and landing. However, the landing gear of the existing rotor UAV is a little strict to the terrain. When landing on the special terrain, the UAV often rollover because of the uneven ground, which may cause huge economic losses. Based on the traditional design scheme of landing gear for unmanned aerial vehicle （UAV） and according to the requirements of terrain adaptive scene, the design changes of landing gear damping spring and free telescopic mechanism are proposed in this paper. Through the analysis of the key parameters, the feasibility of the project and the improvement of terrain adaptation are verified.
