Building teaching earthquake simulation device for earthquake prevention

Abstract

The invention relates to a building teaching earthquake simulation device for earthquake prevention, which comprises a base, a moving table is arranged on the base, the bottom side of the moving table is fixedly connected with one ends of a plurality of parallel first spring rods, the top side of the base is fixedly connected with one ends of a plurality of parallel second spring rods, and the first spring rods are perpendicular to the second spring rods. The other end of each first spring rod is fixedly connected with the other end of the corresponding second spring rod through a supporting rod. The device is simple in structure and ingenious in conception, the moving table can reciprocate in the plane at any angle through the driving device, transverse wave vibration simulation in different directions can be carried out on a building, the vibration amplitude can be adjusted, vibration simulation of different vibration intensities can be carried out, market requirements can be met, and the device is suitable for popularization.

Description

Technical field [0001] The present invention belongs to the field of seismic simulation apparatus, particularly apparatus for seismic modeling construction teaching seismic prophylaxis. Background technique [0002] Shaking table is for mechanics, earth science, engineering and technology disciplines scientific basis of physical performance test equipment, teaching building, usually the building model using the simulated seismic shaking table, because the seismic waves are divided into: longitudinal waves, shear and surface waves, wherein the longitudinal wave occurs that the vertical vibration of the ground, less damaging, front and rear transverse surface occurs, about jitter, destructive strong, therefore the time of construction is generally carried out only shear seismic modeling simulation, conventional seismic vibration simulation platform is generally only possible in two directions transverse wave analog cross, whereby the building can not multi-angle vibration simulatio...

AI Technical Summary

Problems solved by technology

[0002]Earthquake simulation shaking table is a physical performance testing instrument used in the basic disciplines of mechanics, earth science, engineering and technical science. In construction teaching, earthquake simulation is usually used The shaking table performs anti-seismic simulation on the building model. Since the seismic waves are divided into longitudinal waves, transverse waves and surface waves, the longitudinal waves cause the ground to vibrate up and down, which is less destructive, and the transverse waves cause the ground to vibrate back and forth, left and right, which is more destructive. For building earthquake simulation, only shear wave simulation is usually performed. The existing seismic vibration simulation platform can only perform shear wave simulation in two cross directions, so it is impossible to perform multi-angle vibration simulation for buildings, and the swing amplitude of buildings is generally fixed. No change, no adjustment, no vibration simulation with different vibration intensities, we meet the actual needs, so we invented a building teaching earthquake simulation device for earthquake prevention
