    Abstract

    Magnetic shape memory alloys (MSMA) are adaptive materials controlled with a magnetic field. A fast response, large magnetic field induced strain and high damping make MSMAs attractive materials for actuators. The aim of this study was to define the characteristics of a MSMA actuator and evaluate its suitability for vibration control. The results indicate that the MSMA actuator is suited for adjusting stiffness and damping of mechanical systems.
