Abstract

The invention relates to a space microgravity double-layer suspension vibration isolation device, a scientific experiment cabinet and a suspension method. The space microgravity double-layer suspension vibration isolation device includes an air-jet suspension test bench (abbreviated as an outer body), a magnetic levitation test bench (abbreviated as an inner body), and an inner body The body is provided with a magnet, the outer body is provided with an electromagnetic coil, the inner body is embedded in the outer body, the magnet and the electromagnetic coil are arranged correspondingly, and the force generated by the energized coil in the magnetic field is used to control the suspension of the inner body relative to the outer body; The thruster utilizes the jet stream of the thruster to generate thrust to control the suspension of the outer body. The invention realizes the double-layer non-contact movement of the outer body following the inner body from the hardware level, and isolates the disturbance of the basic environment, thereby realizing a high microgravity level.

Description

technical field [0001] The invention relates to the technical field of space microgravity, in particular to a space microgravity double-layer suspension vibration isolation device, a scientific experiment cabinet and a suspension method. Background technique [0002] In the field of manned spaceflight, people use the weightless environment in the space station that has been in orbit for a long time to carry out a variety of scientific experiments such as basic physics and fluid physics. Due to the influence of various disturbance forces generated in the process of orbit, transient acceleration, and rendezvous and docking, the microgravity level cannot meet the requirements of scientific experiments. [0003] Therefore, how to isolate or eliminate various disturbances as much as possible and create a higher microgravity environment for space science experimental research has become an important topic of space application technology. [0004] At present, judging from the appl...
