Multipurpose initiative controllable large-output vibration insulating and damping device

Abstract

The invention relates to a multipurpose initiative controllable large-output vibration insulating and damping device. The multipurpose initiative controllable large-output vibration insulating and damping device mainly comprises a tapered working module and a disc type anti-torque working module, wherein the tapered working module comprises a concave magnetic permeating plate, a support rod, a magneto-rheological elastomer composite magnetic permeating plate, an annular magnet exciting coil I, an annular permanent magnet I, a longitudinal magnetic permeating ring and a large-deformation soft magnet, and the disc type anti-torque working module comprises a large fixed ring pressing column, an A positioning angular contact ball bearing, an anti-shearing magnetic permeating disc, an annular magnet exciting coil II, an annular disc type permanent magnet II, a bearing seal, a B positioning thrust ball bearing and a base groove. A variable cross-section central rod is reasonably arranged to work in cooperation with the tapered working module and the disc type anti-torque working module. On the aspect of civil engineering, the problems that an existing vibration insulating device for civil construction is insufficient in rotating capability, low in tension resistance, weak in vertical vibration resisting capability, incapable of simultaneously meeting requirements on horizontal and vertical vibration resisting capabilities and the like.

Description

technical field [0001] The invention discloses an actively controllable large-output shock-isolation and vibration-reduction device, which is mainly used for the hybrid control of shock-isolation and vibration reduction of civil structures, the hybrid control of shock-isolation and vibration reduction of special vehicle suspensions, or the hybrid control of shock-isolation and vibration reduction of vibration table bases , which belongs to the field of structural vibration control. technical background [0002] Vibration problems widely exist in various fields of national production, especially in civil engineering and automobile fields. In the field of civil engineering, base isolation is the main vibration problem of civil construction. Base isolation technology is mainly used in buildings with high or special requirements for seismic safety and use functions (national standard GB5001-2010 "Seismic Design of Buildings") Section 3.8.1 of the Specification). As the seismic...

AI Technical Summary

Problems solved by technology

Vehicles traveling over rough terrain are prone to large pitch rolls, which can adversely affect vehicle durability, stability, and the operator's working conditions

Wheel offset allows the vehicle to drive more stably on bumpy roads, but the torsion bar spring suspension of tracked vehicles limits the vehicle's maneuverability due to its linear nature and resulting poor drivability
