Embodiment Construction

[0024] The structure of the two-direction three-degree-of-freedom spring-type earthquake simulation shaking table of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] The optional test piece weight of the spring-type earthquake simulation vibration table of the present invention: 3kN, 6kN, 9kN, 12kN; vibration frequency 2~6Hz, maximum amplitude 50mm, its structure as shown in Figure 1, Figure 2, Figure 3, including support Frame, test bench 9, the excitation system that makes the test bench simulate an earthquake. The support frame is composed of an outer support frame 1 and an inner support frame 2 located in the outer support frame. The vibration excitation system is mainly composed of a platform 6 , a horizontal vibration excitation system, a vertical vibration excitation system and a clamping mechanism 3 .

[0026] The translation platform 6 includes a platform body and a roller group installed at the bottom of t...

Abstract

A two direction free vibration table in spring type consists of support frame, test table, exciting system to make test table simulate earthquake. The su0pport frame is formed by outer support frame and inner support frame and the exciting system is composed of level exciting system including level spring set connected to translation table and inside face of outer support frame, vertical exciting system including vertical spring set connected to translation table and test table bottom as well as clamping mechanism.

Description

technical field [0001] The invention relates to an earthquake simulation vibration table used in structural earthquake experiments. Background technique [0002] The research on seismic vibration simulation methods and supporting shaking tables for structural earthquake experiments has a history of several decades. So far, mechanical, electromagnetic, and servo-hydraulic earthquake simulation shaking tables have come out and been put into use. In structural earthquake experiments Play a role. However, the structure of the mechanical seismic simulation shaking table is complicated, and the price of the electromagnetic and servo-hydraulic seismic simulation shaking table is expensive, which hinders popularization and promotion, and will inevitably affect the development of earthquake research and prediction work. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a two-way three-degree-of-free...
