An active damping vibration isolation support device

Abstract

The invention discloses an active damping and vibration-isolation support device, which comprises: a lower base and an upper base arranged on the lower base, wherein the lower base includes a lower base plate of the lower base, and a lower base force transmission device is installed in the center of the lower base plate of the lower base. The core column, the top of the lower base force transmission core column is equipped with the upper top plate of the lower base; the upper base includes the upper base upper plate arranged on the upper base plate of the lower base, the outer wall of the upper base is installed on the upper plate of the upper base, and the lower end of the outer wall of the upper base The lower end plate of the upper base is installed; the outer part of the force transmission core column of the lower base is covered with a piezoelectric stack; the upper end of the piezoelectric stack is provided with a first force transmission backing plate, and the lower end of the piezoelectric stack is provided with a second force transmission backing plate. The present invention can not only effectively block the transmission of ground vibration to the upper structure of the support and the transmission of the vibration of the upper structure to the foundation, but also consume vibration energy through the friction layer, and has clear force transmission path and strong adaptability to the environment Etc.

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 support 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...
