摘要
针对物流无人机起降平台需要在大风条件下进行作业的问题,设计了一种起降平台的天窗开合装置,该装置能够防风防雨并为物流无人机起降平台内部结构提供保护。建立了天窗开合装置的三维模型,并利用Matlab软件进行运动学分析,验证了设计的可行性;分析了机构受力情况,并用SolidWorks对虚拟样机进行了动力学分析,选择合适的电动推杆作为驱动;对模型进行简化并对天窗机构进行了流固耦合有限元分析,验证了天窗开合装置在大风天气下的抗风能力;进一步仿真模拟了在风载荷作用下的天窗开合运动过程,校核了其在大风条件下的工作能力。优化后的天窗开合装置能够在静态条件下承受7级大风,并能够在5级大风下正常工作。
For the problem that the logistics UAV(unmanned aerial vehicle) takeoff and landing platform needs to operate under windy conditions, a skylight opening device for the takeoff and landing platform was designed, which can protect the internal structure of the logistics UAV takeoff and landing platform from wind and rain.The 3 D model of the skylight opening device was established, and the kinematic analysis was carried out by Matlab to verify the feasibility of the design;the force situation of the mechanism was analyzed, the dynamics of the virtual prototype was analyzed by SolidWorks, and a suitable electric actuator was selected as the drive;the model was simplified and the fluid-structure coupling finite element analysis of the skylight mechanism was carried out to verify the wind resistance of the skylight opening device in windy weather;further simulation of the opening motion of the skylight under wind load was carried out to verify its working capability in windy conditions.The optimized skylight opening device can withstand wind force 7 under static conditions and work normally under wind force 5.
