The invention provides a pneumatic suspension system for simulating a zero-gravity environment and a control method. The pneumatic suspension system comprises a supporting assembly, a suspension assembly and a control system. The supporting assembly comprises a box, a top plate and a spindle, the top plate is arranged in the box, vertical guide rails are arranged on two sides of the box, the spindle penetrates through the top plate and the box bottom, and the top is used for hanging a tested object. The suspension assembly comprises a beam, a cylinder barrel, an air floatation piston, a piston rod and an air source, the beam slides along the guide rail, an airflow channel is arranged in the beam and connected with the air floatation bearing, the air floatation piston is arranged in the cylinder barrel, the cylinder barrel is divided into an upper cavity and a lower cavity, the upper cavity is communicated with the atmosphere, the air source supplies air to the lower cavity, and the two ends of the piston rod are connected with the air floatation piston and the beam respectively. And the control system controls the gas transmission work of the gas source. According to the pneumatic suspension system, friction of the system is effectively reduced, dynamic self-adaptive balance is achieved through the control system, and therefore the more accurate and stable suspension effect is provided.

    本发明提供了一种用于模拟零重力环境的气动悬浮系统及控制方法,包括支撑组件、悬浮组件和控制系统。支撑组件含箱体、顶板及主轴,顶板内置于箱体,箱体两侧有竖直导轨,主轴贯穿顶板与箱底,顶部用于悬挂测试物体。悬浮组件包括横梁、缸筒、气浮活塞、活塞杆和气源,横梁沿导轨滑动,内部设有气流通道连接气浮轴承,缸筒内置气浮活塞,将缸筒分为上下腔室,上腔室连通大气,下腔室由气源供气,活塞杆两端分别连接气浮活塞和横梁。控制系统控制气源的输气工作。本发明所述气动悬浮系统不仅有效减少了系统本身的摩擦,还通过控制系统实现了动态自适应平衡,从而提供了更为精准和稳定的悬浮效果。
