Subsurface stress field beneath the cam-roller contact surface under elastohydrodynamic lubrication and tangential loading

탄성유체윤활 및 접선하중 상태에서 캠-롤러 접촉표면의 내부 응력장

For cam and roller-follower contacting surfaces, the effect of tangential loading on the subsurface stress field at an elaso-hydrodynamic lubrication condition has been studied numerically. As tangential load increases, the subsurface stress field extended more widely to the direction of the tangential load. The positions of the maximum shear stress and the maximum effective stress are getting closer to the surface with the increasing tangential load. The tangential load at the elasto-hydrodynamic lubrication condition is of little consequence to the subsurface stress field.
