Fretting fatigue test method and fretting fatigue test apparatus

摘要

PROBLEM TO BE SOLVED: To provide a fretting fatigue testing method that can generate a fixing region and a sliding region in a contact surface where a contact piece and a test piece are in contact with each other and precisely measure fretting fatigue characteristics.SOLUTION: The fretting fatigue testing method includes the steps of installing a pressing member 14 to a pair of pads 11 and pressing a test piece 3 with the pressing member 14 by tightening a bolt 12 penetrating the pads 11, and applying high-frequency torsional vibration to the test piece 3 to perform fatigue test.
