Vacuum cabin for aerospace environment simulation

Abstract

The invention relates to the technical field of aerospace environment laboratories, and discloses a vacuum cabin for aerospace environment simulation. The vacuum cabin comprises a cabin body, an extrusion toothed bar is inserted in the side surface of the cabin body, a bearing plate is fixedly connected to one side, located in the cabin body, of the extrusion toothed bar, a support spring is fixedly connected to one side, close to the inner wall of the cabin body, of the bearing plate, the side face of the extrusion toothed rod is in engaged connection with a bearing wheel, and the lower portion of the bearing wheel is rotationally connected with a centrifugal wheel through a belt; and the side face of a delay screw rod is in sliding connection with an extrusion rod, the side, away from awheel center, of an engagement rod is in engaged connection with a conical screw rod, and the side face of the conical screw rod is in engaged connection with a rotating shaft. According to the vacuumcabin for aerospace environment simulation, through cooperative use of the bearing plate and the bearing wheel, the effect that when a person moves in the simulation vacuum cabin, the person is prevented from generating large extrusion force with the wall of the cabin body due to the too high moving speed, and the person is prevented from being injured is achieved.

Description

technical field [0001] The invention relates to the technical field of an aerospace environment laboratory, in particular to a vacuum chamber for simulating an aerospace environment. Background technique [0002] The aerospace environment laboratory is mainly a large-scale simulator that simulates the aerospace environment. It is used for astronauts to adapt to the state of space weightlessness and familiarize themselves with the operation of aerospace instruments. It is also used for scientific research personnel to experiment with new equipment and observe the effects of radiation. It is of great significance for training astronauts to survive and work in a weightless environment. [0003] When personnel are trained in a simulated vacuum chamber, since the personnel will move in the opposite direction of the force after applying a force and cannot slow down, when the applied force is too large, the speed of the personnel will be greater. When the personnel and the cabin T...
