The dynamic force between curved surface and Plane linked by a liquid meniscus bridge was analysed assuming small vibration of the spacing. The infinite width meniscus and the finite meniscus ring were considered as analytical models. The incompressible Reynolds equation was solved under the Laplace pressure boundary condition and the solution was linearlized by the small vibration assumption. The derivation of the solutions and the differences by the models were discussed. It was found that the pressure and the load carrying capacity in the linearlized analysis had three terms, i.e., squeeze term by the viscosity of liquid, spring term by the dynamic Laplace pressure and static meniscus force term. Comparisons of the variable contact angle model with the variable boundary position model were also discussed.
