Description

Technical Field

[0001] The invention relates to the technical field of earthquake simulation experimental devices, in particular to an earthquake simulation experimental device and a use method thereof. Background Art

[0002] The earthquake simulation experiment device is a complex device used to simulate the earthquake process. It can reproduce the vibration and destructive effects of an earthquake. Through the earthquake simulation experiment device, researchers can observe and analyze the response of buildings, bridges and other structures under the action of earthquakes, so as to find ways to improve their earthquake resistance. Therefore, in order to conduct earthquake simulation experiments more conveniently, we propose an earthquake simulation experiment device and its use method.

[0003] The prior art also has the following defects during use:

[0004] The earthquake simulation experimental device in the prior art can only apply vibrations in different directions to stationary objects when conducting earthquake simulation experiments. When an actual earthquake occurs, different focal depths have different effects on buildings on the ground. The traditional earthquake simulation device has a relatively single function and does not have a simulation function for the focal depth. Therefore, the traditional earthquake simulation device has limitations in the experimental process.

[0005] When simulating an earthquake, the earthquake simulation experimental device in the prior art is different from the buildings on flat ground, such as buildings with complex terrain or built on mountains or slopes, because the impact during the earthquake is different from that of buildings on flat ground, and therefore the earthquake-resistant structure is also different. When simulating an earthquake, the traditional earthquake simulation device can only conduct simulation experiments on the earthquake-resistant structure of flat ground buildings, which limits the scope of application of the earthquake simulation experimental device.
