Earthquake Shaking Table Teaching System

Product Description

There are three types of Earthquake shaking tables: hydraulic type, mechanical type, and electromagnetic type. An earthquake shaking table is an indispensable device in structural earthquake resistance, natural frequency measurement, vibration analysis. The cost of a shaking table depends on its size, performance, and the corresponding supporting equipments. Generally it costs several hundred thousand to over a million dollars to build one shaking table and the maintenance costs are high. Therefore, it may be too costly for many institutions and new institutions of science and engineering to buy such equipment. Even they could afford and purchase such equipment, it would still be difficult and unsuitable for it to be used for general teaching purposes. The "NAWS-Z*0 earthquake shaking table system" produced by our company is specially designed for institutions of science and engineering. It has nearly the same features and exactly the same content of experiment of a large vibration table but with much lower costs. It is very suitable for teaching. It enables students to study through experiments, to understand and master the methods needed in vibration experiments, thus laying the foundation of their future involvement for the construction of medium or large vibration tables. Contents of Experiment (1) Earthquake simulation; Generation and Application of an Artificial earthquake wave; Calculation of the accelerating response spectrum (2) Test of structural modal shape by the excitation of white noise (3) Beat wave simulation (4) Sine wave simulation (5) Random waves simulation
