Squeeze film phenomena are investigated numerically and experimentally when the intervening fluid is compressible and the squeezing surface is a compliant one. From the previous studies, it is known that in a sinusoidally oscillating squeeze film, positive mean load-carrying capacity is generated when the fluid is compressible. In an incompressible fluid, load-carrying capacity is generated when the squeezing surface is a compliant one or squeeze action is very rapid. In this study the effects of both compressibility of fluid and surface elasticity are investigated. In the numerical analysis, the Reynolds equation for compressible fluid and the equation of elasticity are solved by the finite difference method and Newton-Raphson method. In the experimental study, squeeze action is generated by an electric vibrator and load-carrying capacity is examined for rigid and compliant surfaces.
