MULTIAXIAL FRETTING WEAR TEST APPARATUS USING MAGNETOSTRICTION ELEMENT

摘要

A multiaxial fretting abrasion testing device using a magnetostrictive element of the present invention includes a first magnetostrictive vibration unit (210) applying frequency vibration to a specimen (S) in an X-axial direction of the specimen (S); a second magnetostrictive vibration unit (220) applying frequency vibration to the specimen (S) in a Z-axial direction of the specimen (S); a specimen holder (250) joined to the first magnetostrictive vibration unit (210) and the second magnetostrictive vibration unit (220) and having the top surface in contact with the surface of the specimen (S); a specimen fixing unit (300) placing the specimen (S) on the specimen holder (250); an induction coil fixing unit (400) positioned on the specimen holder (250) to cover the specimen (S) positioned on the specimen holder (250) and heating the surface of the specimen (S); a measuring module (500) detecting a load, the displacement, and a frictional force due to frequency vibration and heat; and a data processing unit (600) calculating fretting abrasion/fatigue of the specimen based on the information provided by the measuring module (500).
