Název v původním jazyce

Semi-analytical approach for ratcheting strain and wear prediction on case of line rolling contact

Popis výsledku v původním jazyce

The most studies in the field of rolling contact fatigue and wear consider that these phenomenons are independent, but this paper shows strong coupling of both in the case, when ratcheting mechanism is the driving one. There is presented the applicationof semi-analytical approach, introduced by A. Mazzu, for two dimensional rolling contact case. The model is based on non-linear kinematic and isotropic hardening rule of Chaboche and Lemaitre. Mazzu´s approach has been modified to correctly predict ratcheting and wear rate for different values of contact pressure. A correlation between the parameter ?L (yield stress) and the value of the maximum contact pressure p0 has been found. All performed simulations are based on rolling contact fatigue tests realized on author´s department.
