Magnetostrictive Active Control System: Actuator anchorage + control sensor

The design and construction methods employed for the magnetostrictive actuators represents a step forward in the state-of-the-art for this technology; they are at present the largest manufactured in Europe. Although their performance will not meet the overall project objective of damping the whole mock-up structure by the incorporation of the actuators in series with the main stay cables, useful damping of the cables has been achieved with a parallel system. In addition, the practical, application specific, information arising from the mock-up tests, together with general advances in the technology anticipated in the relatively near future, has provided the basis for further exploitation of magnetostrictive technology in this and a range of other market sectors.
