Magnetoelastic Measurements in High-Speed Steel Torque Transducers


Speaker: Professor Mark S. Boley
Date: January 29, 2010 (Friday)
Time: 4 p.m.
Room: 205 Currens Hall

Abstract:
In this presentation, I will attempt to explain the basic physics background and some of the historical development of current magnetoelastic torque sensing technology from the perspective of undergraduate-level physics. The group of measurements that are fundamental to understanding the interplay between the magnetic field and the elastic field in these high-alloy steels will also be discussed, along with an explanation of the instrumentation used. While the initial discussion will center around the macroscopic group of measurements, as time permits we will also consider some of the possible microscopic measurements. Special attention will be given to the many opportunities that this fairly low-budget research provides for both undergraduate and graduate students to develop basic physical measurement and instrumentation skills that are so essential in any research connected to industry.
