Stress Analysis on the Cam-Roller Contact Parts in a Marine Diesel Engine

박용 디젤기관 캠-롤러 접촉부의 응력 해석

The subsurface stress field beneath the roller due to the lubricant film pressure acting on the roller surface has been calculated. Main purpose of this study in view of engineering is to prove the validity of the numerical profile roller presented by Koo et al who obtained the lubricant film pressure by elastohydrodynamic lubrication analysis on the cam-roller mechanism. The stress field for the numerical profile roller was compared with the one for the existing dub-off profile roller.
