The invention relates to a four-degree-of-freedom satellite simulation device which comprises a base body frame, an air foot, a nozzle, two fixed pulley blocks, a target load counterweight assembly, two reverse counterweight assemblies and a pressure system. The first ends of the two fixed pulley blocks are respectively connected to a target load counterweight assembly through ropes; the second ends of the two fixed pulley blocks are connected to the two reverse counterweight assemblies through ropes correspondingly. Gravity balance of the target load assembly in the vertical direction is achieved through the two reverse counterweight assemblies. The air supply on-off time of the pressure system to each nozzle is set according to the posture adjustment requirement, so that the device realizes the position and posture control of four degrees of freedom of translation along the X axis, the Y axis and the Z axis and rotation around the Z axis. Microgravity simulation of the satellite on the ground is achieved, meanwhile, four-degree-of-freedom control over the position and attitude of the satellite is achieved, and a hardware basis is provided for ground tests.

    本发明涉及一种四自由度卫星模拟装置,包括基体框架、气足、喷嘴、两个定滑轮组、目标载荷配重组件、两个反向配重组件、压力系统;两个定滑轮组的第一端分别通过绳索连接到目标载荷配重组件;两个定滑轮组的第二端分别通过绳索连接到两个反向配重组件;通过两个反向配重组件实现目标载荷组件在竖直方向的重力平衡。按照姿态调整需求设置压力系统对各个喷嘴的供气通断时间,使所述装置实现沿X轴、Y轴、Z轴的平移以及绕Z轴的转动这四个自由度的位置与姿态控制。本发明实现了卫星在地面上的微重力模拟,同时还实现了对卫星位置、姿态四自由度的控制,为开展地面试验提供硬件基础。
