Design of Test Stand for Magnetic Shape Memory Alloys Samples and Representation of Obtained Results

摘要

Materials with magnetic shape memory gained recognition for their greatest elongation in a group of smart materials, which reaches 10%; another advantage is high operating frequency. Disadvantages must also be considered, these are hysteresis, temperature sensitivity, other nonlinearities and high price. High strain makes it possible to use these materials in actuators design, but it is also possible to apply MSMA in energy harvesters and sensors. This article is linkage between physico-chemical R&D work and basic design of a transducer. Design of a test stand was described, different research scenarios were presented and to sum up this work graphs with the obtained results were placed.
