Abstract

The invention belongs to the technical field of geotechnical engineering, and in particular relates to a single-degree-of-freedom vibration table test device. It consists of the base, the front and rear fixing brackets of the vibration exciter, the horizontal and vertical suspension beams, the suspension fixing rods, the vibration exciter (fixed support, oil cylinder, dowel bar, connecting bayonet device), the vibration table track support, the track, and the vibration table table , fixed hole, rollers at the bottom of the vibrating table, vibrator servo system, hydraulic transmission control system, and computer adjustment control system. The front and rear fixed brackets and longitudinal and transverse suspension beams are fixed on the base to form a frame to fix the vibration exciter oil cylinder. The vibration table is placed on the instrument support through the rails. The vibration exciter is rigidly connected to the vibration table. Servo system, oil Pressure system and computer system for operation control. The invention can realize the simulation of earthquake vibration under the excitation of the set waveform by combining with different shaking table model test devices, so as to carry out the vibration mechanism test research of the scientific problems of geotechnical engineering under single-degree-of-freedom 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...
