摘要
基于对国内外物流无人机的研究发现,无人机的承重程度以及续航能力等存在缺陷,针对这一系列问题,对物流无人机进行改善,夹爪式拾取设计、起落架收放设计以及对内部空间镂空设计等优化,在减轻自身重量的同时,有效提升续航能力,采用Arduino开发板和飞控对执行飞行任务进行控制,选择型号为TYI-5008 KV400无刷电机提供升力,顶部装载有小型规格太阳能板对无人机进行辅助供电,并用大容量锂电池保证无人机长时间续航。根据以上设计和选型完成各个部位的组装以及各个系统的调试,各个模块任务均能同时进行。利用SolidWorks对主要承重零件进行力学仿真,零件选用碳纤维材料,并从上方施加500 N的力,随后利用运动分析结果,得出其应力变化、位移变化以及应变变化,均能达到预期实验效果。
The research on domestic and international logistics UAVs indicates found that there are deficiencies in the load-bearing capacity and endurance of drones.In view of these problems,the logistics UAVs are improved,including claw pickup design,landing gear retraction design and hollowing out design in the internal space,so as to reduce their own weight and effectively improve the endurance.Arduino development board and flight control are used to control flight tasks.The model TYI-5008 KV400 brushless motor is selected to provide lift.A small solar panel is mounted on the top to provide auxiliary power to the UAV.According to the above design and selection,the assembly of each part and the debugging of each system can be completed,and each module task can be carried out at the same time.SolidWorks Simulation is used to conduct mechanical simulation of the main load-bearing parts.Carbon fiber materials are selected for the parts,and 500 N gravity is applied from above.Then,the stress changes,displacement changes and strain changes are obtained by using the results of motion analysis,which can achieve the expected experimental results.
