Abstract

The utility model relates to a gravity unloading device for three-dimensional active movement of an air floating support, which belongs to the technical field of microgravity simulation equipment. The invention solves the problem that the existing microgravity simulation equipment is not suitable for large-load unloaded objects. The movement of each air bearing block on its corresponding air bearing guide rail is realized by a linear motor. The electric cylinder type unloading mechanism includes a connecting frame, an angle sensor, a tension sensor and an electric cylinder. The connecting frame is fixed on the second At the bottom of the air float, the angle sensor is installed horizontally on the connecting frame, the electric cylinder is located below the angle sensor and is fixed to the angle sensor through a tension sensor, and the unloaded object is fixed on the piston rod of the electric cylinder through a wire rope bottom end. The two-dimensional motion is driven by a linear motor with fast response and high precision, suitable for large and heavy-duty equipment. The vertical direction adopts the electric cylinder type gravity unloading mechanism to complete the gravity unloading task of the experimental equipment.

Description

technical field [0001] The invention relates to a gravity unloading device for three-dimensional active movement of an air flotation support, which belongs to the technical field of microgravity simulation equipment. Background technique [0002] There are many kinds of microgravity simulation equipment, and the common ones are drop tower method, air flotation method, suspension method and so on. Among them, the drop tower method has a short experimental time and high cost, the air flotation method is only suitable for microgravity simulation in a two-dimensional plane, and the suspension method uses a pulley mechanism and steel wire suspension, so the experimental accuracy is low. [0003] Patent 201810449903.6 provides a microgravity simulation method using a combination of pulley block, air bearing, and suck-back plane bearing. Its movement in the horizontal direction is gas-lubricated and has the characteristics of no friction, but its movement depends on the slewing mec...
