摘要：In the paper, is present the shaking table designed for the laboratory use, to simulate the earthquakes behaviors. Wi th this equipment we can study the dynamic behavior of civil engineering structures subjected to seismic motion. The vibratory movement of the shaking table is carried out by means of an electric motor which, through a crank mechanism, moves the shaking table. The smooth start of the shaking table and its movement is accomplished through a frequency converter, FRENIC-Mini series of general use, made by Fuji Electric C. Ltd. Tests was performed using a NI application with a laser displacement sensor, in order to find out the displacement precision.
