摘要
针对车载无人机起降平台,研究车辆在静态和动态时车载无人机的托举升降和全向调平,设计三自由度的车载无人机升降调平装置,利用单动双丝杆滑块作为大行程升降执行机构,运用三自由度平台的俯仰和横滚动作,使底座在任意方位、一定角度倾斜时,3个伺服电动缸控制平台至恒定水平姿态,为车辆在全地形驻车和行驶中起降无人机提供可靠平台。
As to on-board UAV taking off and landing platform,the lifting and all-directional leveling of the on-board UAV in static and dynamic status is studied,and lift-leveling device of on-board UAV based on three degrees of freedom is designed.A single-driven double screw slider is used to complet large displacement lifting actuator,and three degrees of freedom platform is used to perform pitching and rolling movement,which enables the three servo electric cylinders to control the platform in a constant horizontal posture when the base is inclined in any direction and at limited angle.Thus providng a reliable platform for UAV operation as vehicles are parking or driving in any terrain.
