新型三维隔震装置力学性能试验研究

基于铅芯橡胶隔震垫、组合碟形弹簧和钢板阻尼器的各自力学性能特点,设计开发出一种新型的三维隔震装置,首先简要介绍了该三维隔震装置的组成构造和力学性能设计方法;通过一足尺三维隔震装置分别进行了水平向和竖向力学性能试验。试验结果表明,该三维隔震装置具有构造合理、传力机制明确等优点,在水平向和竖向都能够具有适宜的隔震刚度和阻尼耗能性能,并且在较大水平剪切变形时仍具有良好的整体稳定性。

Mechanical Performance Tests of a Novel Three-dimensional Isolation Bearing

A novel three-dimensional isolation bearing (3DIB) was proposed, based on respective mechanical characteristic of lead rubber bearing, combined disc springs and rhombic steel plated damper. Firstly, the configuration department and mechanical design methodology was introduced; the horizontal and vertical stiffness and energy dissipation performance test was performed on a full scale three-dimensional isolation bearing, respectively. The results indicated that the proposed three-dimensional isolation bearing has reasonable configuration and explicit mechanical transmission mechanism; appropriate stiffness and energy dissipation performance can be achieved by reasonable design, keeping favorable holistic stability at plentiful horizontal shear displacement.
