A numerical solution of elastohydrodynamic lubrication of line contact in combined rolling and normal squeeze motion is presented. The solution is obtained under the condition that the normal squeeze motion is instantly applied to the steady elastohydrodynamic contact between a rolling cylinder and a plane. The effect of surface waviness on the elastohydrodynamic line contact is studied as an operative example of elastohydrodynamic lubrication in combined rolling and normal squeeze motion. One of these calculated results is as follows. The initial change in the oil film thickness in a high-pressure area appears in the inlet region. Then the change in the oil film thickness moves toward the outlet region. The approach motion of the cylinder causes a temporary increase in the oil film thickness in a high-pressure area.
