A numerical analysis of the elastohydrodynamic lubrication under high speed and high load has been made for a line contact using a modified Houpert-Hamrock's method in order to examine the characteristics of the lubrication region which is called 'rigid-variable viscosity' in Hooke's chart. Further, the influence of inlet pressure on the lubrication characteristics has been investigated. Results show that the effect of elastic deformation on the film is significant and thus the film thickness in the region is further insensitive to the load than the film thickness formulated by Hhmrock-Jacobson from numerical solutions in the usual elastic variable viscosity (E-V) region. Also, the inlet pressure in the examined region exerts a marked influence on the lubrication characteristics in comparison to that in the typical E-V region and the pressure spike point moves to the inlet direction contrary to the case of the typical E-V region as the load increases. Therefore, the E-V region in Johnson's charts can be separated further into the two regions.
