In the previous paper, the authors investigated the fluctuation of oil-film pressure and the vibration of cylinders caused by a periodical change in the width of the contact surface. The calculated results were obtained by solving a Reynolds equation and an equation of motion of the cylinder simultaneously, on the condition that the load on the cylinder is so low that the elastic deformation is negligible. In this paper, the effect of the contact-surface-width variation on the elastohydrodynamic line contact has been studied by solving the above-mentioned equations with a formula of elastic deformation and with a formula of pressure dependence of viscosity. One of these calculated results indicates that, under the condition of elastohydrodynamic lubrication, the oil film shape is changed with time similar to wave motions.
