摘要:
In the past few years, different advanced magnetic materials have been developed in response to newly introduced applications. Among those advanced magnetic materials, magnetic shape alloys ( MSMA) demonstrated high potential of usage in a wide range of application as those involving actuators, and sensors. In this paper, the utilization of a typical MSMA Adaptamat material in power harvesting applications is investigated. This investigation has been driven by the fact that the magneto-elastic coupling coefficient of the aforementioned material is as high as that of widely used magnetostrictive Terfenol-D. Vector Preisach modeling and experimental investigation have been carried out for an MSMA subject to transverse magnetic field and time-varying axial mechanical stress. Details of the experimental efforts, modeling and corresponding simulation findings are given in the paper.
