Fretting is a structural damage mechanism arising between two nominally clamped surfaces subjected to an oscillatory loading. A critical location for fretting induced darnage has been identified at the blade/disk and blade/damper interfaces of gas turbine engine turbomachinery and space propulsion components. The hightemperature, high-frequency loading environment seen by these components lead ...

INTRODUCTION There is concern regarding the fretting wear of rolling bearings used in various types of machines, especially those that oscillate minutely. Because fretting wear results in the deterioration of the acoustic properties of bearings, rise in the bearing torque, and flaking originating from wear scar, fretting wear has a negative impact on the performance of rolling bearings. Maruyam...
