A device and a method for reducing wind resistance power of a large geotechnical centrifuge are provided. A semicircular tube cylindrical cooling device is provided between an internal side of a high-speed rotor system and a cylindrical shell. A serpentine top semicircular tube cooling plate is provided right above a hanging basket, and return helium gas inlet holes are provided at a center of the top semicircular tube cooling plate. A helium gas in a helium gas storage tank passes through helium gas outlets on the helium gas inlet pipes, and enters a centrifuge chamber from a bottom sealing plate. The helium gas is used to replace air in the centrifuge chamber to reduce the wind resistance power and corresponding energy consumption. No vacuuming is required, so sealing requirements are lower. Heat dissipation equipment is placed inside the centrifuge chamber, and a helium gas circulation wind duct is added.

A housing of a centrifuge having an abutment for a ground on which the housing sits, as well as to a centrifuge. The housing is divided into two parts, i.e. a first housing and a second housing which is connected to the first housing via a pivot bearing, with at least one energy absorber being arranged between the first housing and the second housing, which energy absorber will counteract the forces, in particular the torques, generated in the event of a crash and will absorb the energy of the crash so as to prevent at least the part of the second housing which rests on the ground from moving relative to the ground, which pivot bearing allows the first housing to rotate relative to the second housing against the action of the one or plural energy absorber(s) which is/are separate from the pivot bearing.

Damage caused by displacement of a rotating shaft is prevented with an acceleration sensor. A centrifuge according to the present invention includes a rotor, a driving source that rotates the rotor, a rotating shaft that links the rotor with the driving source, an acceleration sensor, and a control unit. The acceleration sensor outputs a value indicating acceleration in at least two different directions which are orthogonal to an axial direction of the rotating shaft. The control unit obtains a displacement conversion value corresponding to a value, which is obtained by dividing a value which is proportional to acceleration based on a value indicating acceleration and outputted by the acceleration sensor, by a value which is proportional to a square of an angular velocity of the rotor, and stops rotation of the rotor when the displacement conversion value satisfies a displacement determination criterion which is predetermined and indicates that displacement is large.
