INVESTIGATION ON FRACTAL CHARACTERISTICS OF WORN SURFACES OF POLYMER TAPES BY SAND DUST PARTICLES

摘要

Abrasive wear of the polymer tape of ATM(AutoTeller Machine)tribosysteminsand dust environment isbecoming a big probleminits reliableservice[1].There-fore the study of abrasive wear of the thin polymer tape(40μminthickness)in bill processing becomes a neces-sary work in prompting the service reliability of ATMinsand dust environment.Fractal has been accepted a more exact methodover the traditional ones in characterizing the engi-neering surfaces[2-6].Fractal characters have beenhave discovered on the active...
