Abstract

The invention relates to a curtain wall panel earthquake simulation system vibration performance parameter detection device and a method thereof. The detection device includes a vibration table, a fixing base, three laser light sources and three four-quadrant laser detectors, three sets of current and voltage conversion modules, three sets of computation modules, three sets of analog-to-digital converters and a micro controller; a motor is arranged inside the vibration table; the fixing base is in the shape of a cube; three surfaces of the fixing base which are perpendicular to an X axis, a Y axis and a Z axis are provided with a light reflecting plate respectively; the fixing base is in rigid connection with the vibration table through a connection rod; the three laser light sources are arranged above and opposite to the light reflecting plates respectively; and the three four-quadrant laser detectors are respectively arranged above and are opposite to the light reflecting plates. With the curtain wall panel earthquake simulation system vibration performance parameter detection device and the method thereof of the invention adopted, fast and accurate detection of vibration table high-frequency vibration performance parameters can be realized, and therefore, the problem of insufficient detection accuracy is high frequency vibration in an earthquake simulation system can be solved.

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...
