Abstract

The invention relates to an earthquake experiencing device, comprising an experiencing room, a first oil cylinder, an electro-hydraulic servo valve, a hydraulic pressure power source and an oil source auxiliary equipment which is used for guaranteeing constant output of the hydraulic pressure; the experiencing room is arranged on a desk frame; the desk frame can be arranged on a first motion guide in a horizontal slipping way; a rod of the first oil cylinder is in rigid connection with the desk frame; the first oil cylinder is the double-rod cylinder; the first oil cylinder is connected with the electro-hydraulic servo valve which is connected with the hydraulic pressure power source; the hydraulic pressure power source is connected with the oil source auxiliary equipment; the electro-hydraulic servo valve is connected with a seismic modeling controller which is used for calculating a valve port opening signal according to the seismic displacement data and outputting the valve port opening signal to the electro-hydraulic servo valve. The invention provides the earthquake experiencing device which can reproduce the real earthquake well and strengthen the experience effect, and has the advantage of rational structure.

Description

technical field [0001] The invention relates to an earthquake simulation device for people to experience earthquakes Background technique [0002] Earthquake is one of the natural disasters on earth, causing huge casualties and economic losses. my country is an earthquake-prone country. In the circum-Pacific seismic belt and the Himalayas-Mediterranean seismic belt, my country is currently in a seismically active period with frequent earthquakes. Popularizing earthquake knowledge and mastering earthquake prevention and anti-seismic skills are important means to prevent earthquake disasters, and are closely related to everyone. Earthquake experience can be entertaining and educational, and improve the awareness of earthquake prevention and anti-earthquake among the people. Earthquake experience devices are widely used in large science museums, teaching laboratories, earthquake prevention halls, and building materials research exhibition halls. [0003] Traditional earthquak...
