Characteristics of an Experimental MSMA-Based Actuator

Abstract:

Magnetic Shape Memory Alloys (MSMA) constitute one of the newest groups of intelligent materials [. Although these materials have yet to find commercial applications, literature with information on the first pre-prototype actuators can already be found. The mechanism of operation of these actuators is based on the magnetic shape memory effect. During tests, the shifting of piston and current in the coil of the electromagnet were measured. Measurements were synchronized with set courses of this current coil of the actuator. The obtained results made it possible to make static characteristics for constant levels of current, and dynamic curves for constant values of frequency as well as to construct a mathematical model. In this work, the authors have described laboratory tests of an experimental actuator of this type.
