We have tested the fundamental properties of magnetostrictive actuators. In order to apply the smart structures to large-scale structures on the earth such as buildings, actuators which can produce much larger forces are required. Whether the smart structures can be applied to actual buildings or not, depends on performance and costs of large-scale magnetostrictive actuator. In this study, to investigate the performance, a large-scale magnetostrictive actuator which consists 10 magnetostrictive plates of a φ 30×(12)^H mm outer size is tested. Static and dynamic tests were carried out for the large-scale magnetostrictive actuator, showing fundamental properties of the actuator.
