Embodiment Construction

[0034] The structure of a kind of spring-type earthquake simulation vibration table designed by the method of the present invention is shown in Fig. 1, Fig. 2, Fig. 3, comprises bracing frame, test bench 9, the excitation system that makes test bench simulate earthquake. The spring-type earthquake simulation vibration table has three directions and three degrees of freedom, optional specimen weight: 3kN, 6kN, 9kN, 12kN; vibration frequency 2 ~ 6Hz, maximum amplitude 50mm. The support frame is composed of an outer support frame 1 and an inner support frame 2. The vibration excitation system is mainly composed of an upper translation platform 11 , a lower translation platform 2 , a horizontal X-direction vibration excitation system, a horizontal Y-direction vibration excitation system, a vertical vibration excitation system and a phase adjustment mechanism 13 .

[0035] The lower translation platform 2 includes a platform body and a roller group installed at the bottom of the pl...

Abstract

A vibration table simulating earthquake consists of support frame, test table and exciting system to make test table simulate earthquake. It is featured as setting contact roll of bottom translation table (BTT) on outer support bottom rail and contact roll of top translation table (TTT) on BTT rail in exciting system, connecting level Y direction spring set to BTT and inside face of outer support frame, level X direction one to TTT and inside face of inner support frame and vertical spring set to TTT and test table bottom.

Description

technical field [0001] The invention relates to an earthquake vibration simulation method for structural earthquake experiments and an earthquake simulation shaking table for implementing the earthquake vibration simulation method. 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 been published and put into use, and have played an important role in structural earthquake experiments. effect. However, the structure of the mechanical earthquake simulation shaking table is complicated, and the price of the electromagnetic and servo-hydraulic earthquake simulation shaking table is expensive, which hinders popularization and promotion, which will inevitably affect the development of earthquake research and prediction wor...
