Abstract: A vacuum chamber structure of an ultra-high gravity geotechnical centrifuge device, comprising: a cylindrical shell, a convex head, a bottom head, a lower bearing sealing cover, and a vacuum pressure-bearing chamber formed by sealing a top cylindrical cylinder and an upper sealing plate with sealing rings; wherein a high-speed rotor system is enclosed in the vacuum pressure-bearing chamber, and a cylindrical cooling device is installed between an internal side of the cylindrical shell and the high-speed rotor system. An annular cooling device is provided directly above the hanging baskets on both sides of the centrifuge arm. A vibration isolation expansion joint is arranged at the intersection of the high-speed rotor system and the cylindrical cylinder, which isolates the vibration of the main engine from the vacuum chamber and greatly reduces the vibration.

A vibration isolation expansion joint is arranged at the intersection of the high-speed rotor system and the cylindrical cylinder, which isolates the vibration of the main engine from the vacuum chamber and greatly reduces the vibration. The lower bearing and the upper bearing system are placed outside the vacuum pressure chamber, so that the centrifuge operates under vacuum with low power consumption, while the bearing system reliably operates under normal pressure, the present invention is capable of making the gravity acceleration of the ultra-gravity geotechnical centrifuge reach more than 1500 g, and solves the problems of large vibration and difficult heat dissipation of the ultra-high gravity centrifuge.

Abstract: A pressure-control temperature-control hypergravity experimental device includes a high pressure reactor, a hydraulic oil station, a manifold board, a hypergravity water pressure control module, a hypergravity mining control module, a kettle body temperature control module, and a data collection box. The hydraulic oil station is connected to the manifold board and then two paths are formed. The two paths are respectively connected to the high pressure reactor via the hypergravity water pressure control module and the hypergravity mining control module. The kettle body temperature control module is connected to the high pressure reactor. The high pressure reactor, the manifold board, the data collection box, the hypergravity water pressure control module and the hypergravity mining control module are disposed on a hypergravity centrifuge air-conditioning chamber. The hydraulic oil station, a computer and the kettle body temperature control module are disposed outside the hypergravity centrifuge air-conditioning chamber.
