EFFECTS OF PRESSURE AND VIBRATION RATES UPON FRETTING DAMAGE.

Abstract

Steel specimens identical in composition, surface finish, and hardness, lubricated by the same grease were tested at four different vibration rates and three different pressures. The results indicate that an increase in pressure over the range used resulted in increased fretting damage. Results of the vibration frequency tests indicate that the fretting damage is greatest at an intermediate rate and decreases at a higher or lower vibration rate. There is some indication that the load also may have had an influence upon the damage at certain vibration rates. There is apparently an interrelationship between loads and frequencies upon fretting.
