The invention discloses an intelligent following air floatation vehicle for a large space unfolding mechanism, and belongs to the field of spaceflight mechanical structures. The system comprises a gravity unloading subsystem, an intelligent following subsystem, a gas source assembly and a measurement and control subsystem. The upper-layer air foot and the lower-layer air foot of the intelligent following air floating vehicle and the Mecanum vehicle are used for achieving movement of following a large space unfolding mechanism. According to the invention, the lead screw and the Mecanum vehicle are adopted to realize an active mode of intelligently following the air floating vehicle, the mass of the follow-up tool of the large space unfolding mechanism is reduced, the additional resistance and the additional resistance moment are further reduced, and the precision of a ground microgravity simulation experiment is improved. Zero-gravity unloading of the large space unfolding mechanism moving in the vertical direction is achieved through the synergistic effect of the combined bracket, the air floating guide rail and the weight box, in addition, buffering devices are arranged on the weight box and the combined bracket, vibration of the intelligent following air floating vehicle in the following movement process is reduced, and the intelligent following air floating vehicle has the advantages of being stable in movement and high in unloading efficiency.

    本发明公开的一种用于大型空间展开机构的智能跟随气浮车,属于航天机械结构领域。本发明包括重力卸载子系统、智能跟随子系统、气源组件和测控子系统。本发明利用智能跟随气浮车的上层气足、下层气足和麦克纳姆车实现跟随大型空间展开机构的运动。本发明采用丝杠和麦克纳姆车实现智能跟随气浮车的主动模式,减小大型空间展开机构随动工装的质量,进而减小附加阻力和附加阻力矩,提高地面微重力模拟实验的精度。本发明采用组合托架、气浮导轨、配重箱的协同作用实现大型空间展开机构在竖直方向运动的零重力卸载,此外还在配重箱及组合托架部位布设缓冲装置,减小智能跟随气浮车在跟随运动过程中的震动,具有运动平稳、卸载效率高的优点。
