The invention belongs to the technical field of aviation and astronavigation of a ground microgravity simulation experimental platform, and discloses a six-freedom-degree zero-gravity simulation system based on combination of hoisting and air-suspending. A shaft at the other end of a large-diameter coiling block and a shaft at the other end of a small-diameter coiling block are rotationally installed on a base through a second set of air-suspending bearings. The other end of a torque sensor and the other end of a large torque sensor are in transmission connection with a rotary shaft of the small-diameter coiling block through a clutch and a brake. An air-suspending guide rail is vertically installed on a base. After going out of the large-diameter coiling block in a tangent mode, a first sling rope is swerved through a pulley and connected with a platform for a workpiece to be tested perpendicularly in a suspended mode. The workpiece to be tested is horizontally arranged on the upper end surface of a spherical air-suspending bearing, the lower end surface of the spherical air-suspending bearing is arranged on the platform for the workpiece to be tested, and an air tank supplies air to the spherical air-suspending bearing so that the air-suspending bearing can float. The six-freedom-degree zero-gravity simulation system based on combination of hoisting and air-suspending is compact in structure, overcomes the defect that common air-suspending microgravity equipment can not carry out freedom-degree simulation in the vertical direction, and additionally has the function of simulation of hoisting type microgravity equipment on three rotation freedom degrees.
