길들이기 과정을 고려한 변속기용 기어의 접촉피로 수명 예측 = The Contact Fatigue Life Analysis of Transmission Gear considering Running-in

다국어 초록 (Multilingual Abstract)

The contact fatigue life analysis of transmission gear considering run-in process is presented in this paper. The effect of surface roughness change can be calculated by this analysis. To apply "Run-in" process to the contact fatigue life prediction, rolling test results were used. Computational method and the theoretical basis are also discussed. Contact stresses are obtained by contact analysis of a semi-infinite solid based on the use of influence functions; the subsurface stress field is obtained using rectangular patch solutions. Mesoscopic multiaxial fatigue criterion which can yield satisfactory results for nonproportional loading is then applied to predict fatigue damage. Suitable counting method and damage rule were used to calculate the fatigue life of random loading caused by rough surface. As a result of analysis the relationship between the life and the variable roughness is calculated.
