The invention relates to a suspension type six-degree-of-freedom spacecraft dynamics simulation device, and the device comprises a translation guide rail which is installed on a support and can translate in the direction of one degree of freedom of a horizontal plane; one end of the telescopic cantilever is fixedly mounted on the translation guide rail, and the other end of the telescopic cantilever is provided with a fixed pulley and can stretch out and draw back in the other-degree-of-freedom direction of the horizontal plane; one end of the hanging spring is used for hanging the three-degree-of-freedom rotating target, and the other end of the hanging spring bypasses the fixed pulley and is connected to the constant-force unloading mechanism; the three-degree-of-freedom rotating target can perform three-degree-of-freedom free rotation around the ball center of the air floating ball bearing; the constant-force unloading mechanism is mounted on the telescopic cantilever and controls the hanging spring to freely move along with the three-degree-of-freedom rotating target in the vertical direction; the hanging spring inclination angle detection system is used for detecting the inclination angle between the hanging spring and the horizontal plane in the two-degree-of-freedom direction; the computer is controlled to drive the translation guide rail and the telescopic cantilever to move, so that the hanging spring keeps unchanged in the vertical direction in the moving process of the three-degree-of-freedom rotating target; and the constant force unloading mechanism is controlled to complete constant force control in the vertical direction.

    本发明涉及一种悬吊式六自由度航天器动力学模拟装置,该装置包括平移导轨,安装在支架上,能够沿着水平面的一个自由度方向平动;伸缩悬臂,一端固定安装在平移导轨上,另一端端部安装定滑轮,能够沿着水平面的另一个自由度方向伸缩;吊丝,一端用于悬吊三自由度转动目标,另一端绕过定滑轮,连接至恒力卸载机构;三自由度转动目标,能够绕着气浮球轴承球心进行三自由度自由转动;恒力卸载机构,安装在伸缩悬臂上,控制吊丝跟随着三自由度转动目标沿竖直方向自由运动;吊丝倾角检测系统,用于检测吊丝与水平面两个自由度方向的倾角;控制计算机,驱动平移导轨和伸缩悬臂运动,使得三自由度转动目标运动过程中吊丝保持竖直方向不变;控制恒力卸载机构完成竖直方向的恒力控制。
