AI Technical Summary

Technical Problem

The existing vibration isolation effect of dual-control bearings in the vertical and horizontal directions is affected by friction and temperature deformation, resulting in uncertain vibration reduction effect. Furthermore, the vertical and horizontal vibrations are coupled, making independent analysis difficult.

Method used

A method for dual-control vibration support with decoupled horizontal and vertical seismic isolation is proposed, including: the support method under temperature deformation, including: the wear of the support under temperature deformation, and the coupling of vertical and horizontal vibration, which is difficult to analyze independently.

Benefits of technology

By connecting vertical and horizontal seismic isolation devices in series, and using inclined springs and dampers, vertical and horizontal vibrations are decoupled, the wear of supports under temperature deformation is reduced, and the vibration of the connecting corridor under wind-induced or human-induced loads is effectively reduced.

Abstract

The utility model discloses a horizontal vibration isolation and vertical vibration isolation decoupling vibration and vibration double-control support which comprises a vertical vibration isolator and a horizontal vibration isolation device, the vertical vibration isolator and the horizontal vibration isolation device are connected in series up and down, and the vertical vibration isolator is located on one side of the horizontal vibration isolation device. Only the vibration isolation spring is arranged between the upper cover plate and the lower cover plate in the vertical vibration isolator, and a horizontal limiting device does not exist between the upper cover plate and the lower cover plate, so that the vertical vibration isolator has a multidirectional movement trend; the horizontal rigidity of the vibration and shock double-control support is smaller than that of a friction pendulum shock insulation support, the vibration and shock double-control support has the function of energy consumption in the horizontal direction, and when the vibration and shock double-control support is applied to a subway upper cover building or corridor shock insulation structure, abrasion of the support under temperature deformation of a building or a corridor can be effectively reduced; when the device is applied to the corridor, vibration of the corridor under wind-induced or human-induced loads can be effectively reduced.
