Problems solved by technology

For the study of complex geotechnical engineering problems, the multi-degree-of-freedom shaking table can only make the problem more complicated. Therefore, it is necessary to develop a single-degree-of-freedom shaking table suitable for the mechanism research of geotechnical engineering scientific problems under the action of medium vibration.

Abstract

The invention belongs to the technical field of geotechnical engineering and particularly relates to an SDOF vibrating table testing device. The SDOF vibrating table testing device is composed of a base, exciter front and rear fixing supports, transverse and longitudinal suspension beams, suspension fixing rods, an exciter, a vibrating table rail support, rails, a vibrating table top, fixing holes, vibrating table bottom wheels, an exciter servo system, an oil pressure conveying control system and a computer adjusting control system, wherein the exciter is composed of a fixing support, an oil cylinder, a transmission rod and a connecting bayonet device. The front fixing support, the rear fixing support, the transverse suspension support and the longitudinal suspension support are fixed onto the base to form a frame for fixing the oil cylinder of the exciter; the vibrating table top is mounted on an instrument support through the rails; the exciter is in rigid connection with the vibrating table top and is controlled by a servo system, an oil pressure system and a computer system to work. By being combined with different vibrating table model testing devices, the SDOF vibrating table testing device can achieve simulation of seismic vibration under excitation in set waveforms, thereby achieving vibrating mechanism testing study of geotechnical engineering scientific problems under SDOF vibration.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a single-degree-of-freedom vibration table test device. Background technique [0002] Seismic shaking table is one of the important test equipment in the field of seismic research. my country is an earthquake-prone country. In order to adapt to the rapid development of science and technology and the wide application of new materials in the field of geotechnical engineering, more and more research projects require shaking table tests. At present, the mainstream multi-degree-of-freedom shaking table design scheme is basically to study structural engineering issues such as the stability of the superstructure. The seismic research on geotechnical engineering issues mainly focuses on complex mechanisms such as the seismic characteristics and deformation characteristics of the soil under vibration. The question unfolds. For the study of complex geotechnic...
