Characterization of Magnetic Shape Memory Alloys (MSMA) oriented to periodic actuation

Abstract

This paper presents a study of Magnetic Shape Memory Alloy (MSMA) performances oriented to the design of a hydraulic pump. Its main properties, high strain and force under small response time requirement, have been recently improved via acoustic assistance by means of piezoelectric actuation. This research encloses a novel study in MSMA actuation technology regarding force and power mechanical exchanges and power consumption. The aim of this paper is to discuss the convenience of using MSMA technology in driving autonomous hydraulic robot power units.
