The invention discloses a large-stroke gravity unloading device with an adjustable load. The large-stroke gravity unloading device comprises a constant tension mechanism and a supporting frame. The supporting frame is fixed on a low-gravity simulation test platform rapid follow-up system; and the constant tension mechanism is installed on the supporting frame and used for achieving load-adjustable large-stroke gravity unloading. According to the invention, rapid mechanical docking with an existing test rack system can be realized, and low-gravity and microgravity environments can be realized in a landing process of a lander; and the device is simple in structure, large in effective stroke, adjustable in load and suitable for simulating a working condition test that the detector lands on the surface of an extraterrestrial celestial body after an engine is shut down in a low-gravity environment.

    本发明公开了一种可调负载的大行程重力卸载装置,包括:恒拉力机构和支撑框架;支撑框架固定在低重力模拟试验平台快速随动系统上;恒拉力机构安装在支撑框架上,用于实现可调负载的大行程重力卸载。本发明能够实现与已有试验架系统进行快速机械对接,确保在着陆器着陆过程中实现低重力与微重力环境;构型简单,有效行程大,负载可调,适用于模拟在低重力环境下发动机关机后的探测器着陆于地外天体表面的工况试验。
