Test device capable of repeatedly simulating weightless environment

Abstract

The invention discloses a test device capable of repeatedly simulating a weightless environment. The test device comprises a main body bracket, guide rails, a falling device, a winch and an electromagnetic attraction disc device, wherein the guide rails are arranged on a side face of the main body bracket, and the falling device is mounted on the guide rails through a plurality of sliding blocks; the electromagnetic attraction disc device is connected with the falling device through electromagnetic attraction force, and the falling device is connected with a test body; the winch is arranged at one side of the main body bracket, an output shaft of the winch is connected with a steel wire rope, and the steel wire rope is connected with the electromagnetic attraction disc device. The steel wire rope is driven to ascend or descend the falling device through the winch, and buffers which are used for buffering the falling device and the test body are arranged at the bottom ends of the guide rails, so that the test device can effectively realize weightless environment simulation, the use effect is better, and the repeatability and responsiveness of the test device are higher.

Description

Technical field [0001] The invention relates to the aerospace field of simulated environment, in particular to a test device capable of repeatedly simulating a weightless environment. Background technique [0002] With the rapid development of science and technology in China, the weightless environment has a wide range of applications in the aerospace field. At present, many weightless environment simulation facilities are complex and large, with poor operability, maintainability and versatility, and are mainly used by astronauts. In terms of training, due to the limitation of the implementation of weightless environment simulation and the high cost, the existing technology and facilities for simulation of weightless environment are rarely used in product testing, and the existing technology used in the experiment of weightless environment There are few special facilities, which makes it difficult for many aerospace products that require functional verification under on-orbit wei...

Problems solved by technology

[0002] With the rapid development of China's science and technology, the weightlessness environment has a wide application demand in the aerospace field. At present, many weightlessness environment simulation facilities have complex and large structures, poor operability, maintainability and versatility, and are mainly used by astronauts. In terms of training, due to the limitation of weightlessness environment simulation implementation and high cost, the existing technology and facilities for weightlessness environment simulation are rarely used in product testing, while the existing technology used in weightlessness environment testing And there are few dedicated facilities, which makes it difficult for many aerospace products that require functional verification in orbital weightlessness to carry out ground simulation verification tests, which limits the development of aerospace technology to a certain extent.
