 Abstract

In this paper, a theoretical and numerical analysis is presented on the squeezed film between a circular rigid oscillating plate and a fixed proximity surface with an incompressible medium. A series of theoretical methods are derived or reviewed, such as lubrication theory from Reynolds (1886), Kuzma(1967), Ishizawa(1966), Beltman(1997) and Homotopy Perturbation Method(HPM) from He (1998). Numerical analysis is carried out using the Comsol package. A detailed comparison and discussion on the theoretical methods are based on the numerical results from the Comsol simulation. It is found that the hydrodynamic force is governed by the pure squeezing motion of the film height and the difference between the force on the top plate and the force on the bottom plate follows Newton's law. Dynamic models are built based on theoretical models for the mechanical applications.
