摘要
目的设计一种救援人员可随身携带且部署灵活快捷的搜救无人机,以满足战场环境下救援人员对无人机的使用需求。方法利用三维设计软件CATIA完成无人机机体结构设计,充分利用无人机机体内部空间采用可折叠式机翼,减小无人机体积。通过ABAQUS对无人机的关键零部件进行有限元分析与整机的模态分析,验证结构可靠性,并利用机器人仿真软件Webots对无人机进行运动仿真。结果通过仿真分析与试验验证,该无人机结构设计合理,可通过手抛起飞或采用身管式武器发射2种方式进行快速有效的部署,降低了救援人员使用无人机的难度。结论便携式折叠翼搜救无人机的设计与仿真研究对物理样机的研发有着重要意义,为我军救援设备的发展提供了新思路,对无人机小型化的发展也可起到一定的推动作用。
Objective To design a search and rescue UAV that is portable and user-friendly in order to meet the needs of rescue personnel on the battlefield.Methods Three-dimensional design software CATIA was used to complete the structural design of the UAV body.In order to make full use of the internal space of the UAV body,folding wings were adopted to reduce the volume of the UAV.By using ABAQUS,the finite elements of the key parts of the UAV were analyzed before the modal analysis of the whole vehicle was conducted to verify the reliability of the structure.The robot simulation software Webots was used for motion simulation of the UAV.Results Simulation analysis and test verification suggested that the structural design of the UAV was well-grounded.It could be quickly and properly deployed by means of hand launch or barrels,which made it easier for rescuers to use the UAV.Conclusion The design and simulation research of UAVs with portable folding wings for search and rescue is of great significance for the research and development of physical prototypes.This study is expected to stimulate new ideas for the development of rescue equipment in the PLA,and contribute to miniaturization of UAVs.
