Problems solved by technology

Although the air suspension support method has a small footprint, no friction, smooth movement, and high accuracy of microgravity simulation, it can only realize microgravity simulation during one-dimensional and two-dimensional plane motion.
Although the suspension method can realize the simulation of the one-dimensional, two-dimensional and three-dimensional position and attitude of the space mechanism, the truss mechanism supporting the rope is complex and occupies a large space. The rope follower mechanism is generally supported by mechanical bearings, which has large friction and affects Test accuracy

Abstract

The invention relates to intelligent three dimensional microgravity air feet, which pertains to the microgravity simulation experiment device of spatial mechanism. Three air feet are arranged on the lower side of a supporting plate and a shell and three steering bars are arranged on the upper side of the supporting plate. The bottom part and the upper part of the shell are respectively provided with a servo-actuator and an antithrust bearing. A shaft joint and a speed reducer are arranged between the servo-actuator and the antithrust bearing. The lower end of a screw bolt inserted in the antithrust bearing bore is connected with the shaft joint. Transmission nuts matched with three sleeves are arranged on a connection board. A linear bearing is matched with and arranged on the lower end of the sleeve. Three flexible spring mechanisms are connected with a working plate on which a sensor and a joint for a test piece bracket are arranged. The intelligent air feet can effectively solve the technical problem of microgravity simulation during the complicated three dimensional movement of the spatial mechanism and is characterized by simple structure, high simulation precision, flexible test method, simple technique, small floor occupation and convenient debugging, thus being particularly applicable to the microgravity simulation test of complicated three-dimensional movement.

Description

technical field [0001] The invention belongs to a device applied to space microgravity simulation tests, and mainly relates to a microgravity simulation device for complex three-dimensional motion microgravity simulation tests of space mechanisms. Background technique [0002] The existing microgravity simulation methods mainly include the suspension method and the air suspension support method. Although the air suspension support method has a small footprint, no friction, smooth movement, and high accuracy of microgravity simulation, it can only realize microgravity simulation during one-dimensional and two-dimensional plane motion. Although the suspension method can realize the simulation of the one-dimensional, two-dimensional and three-dimensional position and attitude of the space mechanism, the truss mechanism supporting the rope is complex and occupies a large space. The rope follower mechanism is generally supported by mechanical bearings, which has large friction an...
