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 comprises a jet suspension experiment table (outer body for short) and a magnetic suspension experiment table (inner body for short), the inner body is provided with a magnet, the outer body is provided with an electromagnetic coil, the inner body is embedded into the outer body, and the magnet and the electromagnetic coil are arranged correspondingly; the inner body is controlled to suspend relative to the outer body by the acting force generated by the electrified coil in the magnetic field; a thruster is arranged on the outer body, and the thruster is used for jetting airflow to generate thrust to control the outer body to suspend. According to the invention, the double-layer non-contact movement of the outer body following the inner body is realized from the hardware level, and the disturbance of the basic environment is isolated, so that the high microgravity level is realized.

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 disturbing forces generated during 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 experiment research has become an important topic of space application technology. [0004] At present, judging from the application exampl...
