Abstract

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.

Description

technical field [0001] The invention belongs to the field of aerospace technology of a ground microgravity simulation experiment platform. Background technique [0002] In order to reduce the development cost of aerospace equipment, improve reliability, and shorten the R&D cycle, it is necessary to check the entire life of equipment such as equipment functions, performance indicators, work reliability, operating procedures, failure modes, and countermeasures on the ground during the R&D process or before launch. All problems that may be faced during the cycle are verified as efficiently as possible to help designers find design defects as early as possible, modify and verify them, and help operators and managers formulate reasonable operating procedures and reliable emergency response measures , familiar with the operation process. However, since the structural design and material use of aerospace equipment are mostly adapted to low launch load requirements and low-gravity ...
