Shaking Table on One Axis with Electrodynamic Actuator

The paper refers to a shaking table on a single axis designed to test the acceleration sensors used in the evaluation of seismic waves. Studying P waves in order to evaluate the intensity of S waves is a continuous challenge in the field of earthquake research and requires expensive equipment to perform seismic wave simulation, such as shaking table. In this context, it is presented the realization of a shaking table actuated by an electrodynamic actuator of diffuser type controlled by means of a power amplifier. The seismic wave configuration is transmitted to the amplifier via SCPI commands on a computer running a LabVIEW application.
