Abstract: This paper provides the first crosscomparison of three established elastohydrodynamic computational methods to investigate the conformal longbearing pure squeeze cylindrical bearing problem with rigid journal and elastic sleeve. The benefits of each analysis method in addressing both theoretical and practical issues in problem formulation and application are discussed. A set of nondimensional design charts for minimum film thickness and maximum film pressure under a step load are presented. With a judicious choice of load and sleeve geometry, it is found that a uniform film pressure can develop over a large film pocket in the limit of conformal journal and sleeve contact even with relatively high modulus materials such as steel.
