The invention provides an active unloading device for a satellite eccentric two-dimensional turntable load ground expansion test, which comprises a fixed frame connected with a truss, and a moving assembly arranged on the lower side of the fixed frame; the connecting back frame is in fastening connection with a lifting point of the rotary table mechanism, the transfer frames are arranged in the areas, close to a driving shaft and a driven shaft of the rotary table mechanism, of the connecting back frame respectively, and the mass center adjusting disc is arranged on any transfer frame; one screw rod adjusting assembly is rotationally connected to any mass center adjusting disc, the screw rod adjusting assemblies are connected with the hanging beam, the hanging assembly is connected with the middle of the hanging beam, the hanging assembly is connected with the hanging beam and the moving assembly, and the moving assembly allows the hanging assembly to move transversely and/or longitudinally. Unloading is carried out after the device is connected with a satellite two-dimensional rotary table load, the use convenience is improved, accurate balancing and additional motion balance weight are not needed, unloading is carried out at the actual mass center position, the accuracy of simulating the in-orbit zero-gravity unfolding working condition is improved, and more real motion parameters are obtained.

    本发明提供了一种卫星偏心式二维转台载荷地面展开试验主动卸载装置,包括固定框与桁架连接,移动组件设置在固定框的下侧;连接背架与转台机构的吊点紧固连接,转接框在连接背架靠近转台机构的主动轴和从动轴的区域分别设置有一个,质心调节盘在任一转接框上均设置有一个;螺杆调节组件在任一质心调节盘上均转动连接有一个,螺杆调节组件与吊梁连接,吊挂组件与吊梁的中部连接,吊挂组件连接吊梁和移动组件,移动组件允许吊挂组件横向移动和/或纵向移动。通过与卫星二维转台载荷连接后卸载,提高了使用的便捷性,不用进行精确配平,无附加运动配重,在实际质心位置进行卸载,提高了模拟在轨零重力展开工况的准确性,得到更真实的运动参数。
