This paper presents an adaptive control methodology of a shaking table system for earthquake simulators. In the system, reaction forces generated by a specimen deteriorate the table motion performance, resulting in lower control accuracy in seismic tests. In particular, in cases of excitation tests for structures (power facilities, large vehicles, etc.) …

Working Principle. Shaking Table is comprised of head motion, deck, feed and water box and base. The deck is mounted on the supporting base that allows the table to slide along the long axis of the table. A acrylic feed distributing box with hopped and a long water box are attached to the iron of the deck, giving a very even distribution of feed and water.
