Problems solved by technology

[0004] At present, many earthquake simulation devices are realized by hydraulic drive, and its control accuracy, speed and stability are relatively poor
The state of the real earthquake cannot be well realized, resulting in poor physical sensation for people
Many motor-driven structures are complex, inconvenient to operate, and cannot accurately simulate the state of earthquakes of different intensities
Therefore, the technology of the earthquake simulation platform device needs to be improved

Abstract

The invention discloses an earthquake simulation experience platform. The earthquake simulation experience platform comprises a vibration device and an earthquake simulation control system, wherein the vibration device comprises an experience platform, a first support platform, a second support platform and a base; a plurality of support springs are uniformly arranged between the experience platform and the first support platform; a vertical driving device is fixedly arranged between the first support platform and the second support platform, and consists of a servo motor, a ball screw and a telescopic rod; horizontal driving devices are fixedly arranged between the second support platform and the base, and are arranged at the same side; a slide block and slide rail mechanism is arranged between the second support platform and the base; the earthquake simulation control system utilizes a control cabinet which is fixedly arranged on the base; a PLC (programmable logic controller) is used for outputting corresponding data signals to the terminal servo motor via a frequency converter, so as to simulate the earthquake of different intensity. The earthquake simulation experience platform has the advantages that the structure is simple, the property is stable, and the accuracy is high; the real vibration effect during earthquake of different intensity can be simulated.

Description

technical field [0001] The invention relates to the technical field of earthquake simulation equipment, in particular to an earthquake simulation experience platform. Background technique [0002] Earthquakes are a natural phenomenon. The level of an earthquake represents the size and strength of the earthquake itself, which is determined by the energy of the seismic waves emitted by the source, and there is usually only one value for the same earthquake. However, the degree of impact on the ground surface and engineering buildings is strong or weak, and people's feelings are also strong or weak, which is usually expressed by seismic intensity. The ground vibration caused by an earthquake is a complex movement. The fluctuation from the source has two components. The longitudinal wave travels faster and attenuates faster, and the transverse wave travels slower and attenuates relatively quickly. Also slower, longitudinal waves make the ground shake up and down, and transvers...
