Anti-vibration test device of civil engineering structure

Abstract

The invention discloses an anti-vibration test device of a civil engineering structure. The test device comprises a support body, a chassis is arranged over the support body and connected to the support body, the chassis is also connected with an upper carriage via a horizontal slide rail, the upper carriage is connected with a loading box via a vertical slide rail, a horizontal chute is formed in the internal bottom side of the loading box, a slide block is arranged in and connected with the horizontal chute, a linear motor is arranged on the slide block, a motor is also fixed on the slide block and connected with a frequency converter, an output shaft of the motor is provided with a rotating disc, the rotating disc is provided with a position adjustable loading mass block, the loading mass block can be of different specification and dismounted from the rotating disc and replaced, rotary tables are arranged on the loading box, and mounting and clamping device is arranged over the rotary tables; and the test device further comprises a detection component pasted to a test piece and electrically connected with a controller. The test device can simulate vibration influence of earthquake and wind energy on an experimental model, collects and analyzes related data, selects a coefficient of surplus capacity in the design process, provides feasible reference for selection of anti-vibration materials and the like, and is highly practical.

Description

technical field [0001] The invention relates to the technical field of civil engineering experimental devices, in particular to an anti-seismic test device for civil engineering structures. Background technique [0002] The safety responsibility of civil engineering projects is heavy, ranging from economic losses to life safety, so it is very important to do a good job in the safety design of civil engineering. In the design process of civil engineering structures, safety tests for civil engineering structures can be It is very important for design work to provide reliability reference opinions for design. Among the several major factors that endanger the safety of civil engineering, the impact of vibration is the most obvious, and it is particularly important to provide seismic test data. At present, there are many platforms that can provide input methods in a single direction or horizontal and vertical combinations, and conduct seismic tests on civil engineering structure...

Problems solved by technology

At present, there are many platforms that can provide input methods in a single direction or horizontal and vertical combinations, and conduct seismic tests on civil engineering structures, but the data provided by such experiments are not comprehensive, and cannot truly reflect the specific conditions of vibration. , and can simulate the impact of earthquakes and wind energy in nature on the vibration of the experimental model, and collect relevant data, and then send the data to the controller for comprehensive comparison and analysis, and provide the feasibility of the impact of earthquakes and wind energy on civil engineering structures The experimental equipment for the reference data is almost blank, which cannot meet the increasing demand in the design
