Active damping vibration isolation bearing device

Abstract

The invention discloses an active damping vibration isolation bearing device. The active damping vibration isolation bearing device comprises a lower base, and an upper base arranged on the lower base, wherein the lower base comprises a lower base lower baseplate; a lower base force transfer core pole is mounted in the center of the lower base lower baseplate; a lower base upper top plate is mounted at the top of the lower base force transfer core pole; the upper base comprises an upper base upper top plate arranged on the lower base upper top plate; an upper base outer wall is mounted on the upper base upper top plate; an upper base lower end plate is mounted at the lower end of the upper base outer wall; a piezoelectric stack coats the external of the lower base force transfer core pole; a first force transfer cushion plate is arranged at the upper end of the piezoelectric stack; and a second force transfer cushion plate is arranged at the lower end of the piezoelectric stack. The active damping vibration isolation bearing device can effectively stop when solving the transfer of vibration to the upper structure of a bearing and the transfer of vibration of the upper structure to a foundation, and can consume the vibration energy through a frictional layer; and the active damping vibration isolation bearing device has such advantages as definite force transfer path and strong capacity to adapt to environment.

Description

technical field [0001] The invention relates to the field of anti-seismic and mechanical vibration control of civil engineering, in particular to an active damping vibration isolation bearing device. Background technique [0002] When an earthquake occurs, the ground vibration is transmitted to the structure through the support of the upper structure, causing the structure to vibrate. Excessive vibration will damage the structure and affect the safety and applicability of the structure; when the upper mechanical structure is working, it is often Vibration will be generated, which will be transmitted to the ground through the support, causing vibration of other structures or equipment around, and generating noise. Therefore, effective isolation / vibration and noise reduction design is the key to ensure the safety of the superstructure during earthquakes and the vibration and noise reduction of mechanical equipment during operation. The base isolation technology achieves bette...
