Abstract :
A setup for dynamic studies of giant magnetostrictive rods has been developed. The mechanical load on the magnetostrictive rod can be electronically controlled, which makes it possible to study the magnetomechanical behavior in complex situations. Computer simulations show that the setup can be used as a tool for designing magnetomechanical devices. The setup is described, including the mechanical arrangement, sensors, current feed, and data acquisition, and its preliminary operation and verification are discussed
