The dynamic force between solid surfaces linked by a liquid meniscus bridge was analyzed assuming small vibration of the spacing newly. Combined model considering change of contact angle and boundary position was constructed as an analytical model. The incompressible.' Reynolds equation was solved under the Laplace pressure boundary condition and the solution was linearized by the small vibration assumption. Applying the spring constant and damping coefficient of a meniscus derived from the analyses to a mechanical system, the vibration transfer characteristics through a liquid meniscus bridge are analytically clarified and compared with the experimental results. Combination coefficient is derived from comparison between experimental results and theoretical results. Velocity of solid surface increases, then amplitude ratio approachs variable boundary position model.
