Description

technical field

[0001] The invention relates to a detection device for vibration performance parameters of a curtain wall panel earthquake simulation system, and also relates to a method for using the detection device to measure vibration performance parameters of an earthquake simulation system. Background technique

[0002] Earthquake generally refers to the natural vibration of the earth's crust, which is a natural phenomenon like typhoon, rainstorm, flood, lightning, etc. There are about 5 million earthquakes in the world every year, of which more than 50,000 can be felt, about 1,000 earthquakes with a magnitude of 5 or above can cause destructiveness, and about a dozen earthquakes with a magnitude of 7 or above may cause huge disasters.

[0003] The earthquake simulation system is specially developed for the popularization of earthquake knowledge for disaster reduction and prevention. By simulating live earthquakes of various magnitudes, people have an immersive feelin...
