Spring constants and damping coefficients of menisci were obtained from the dynamic force analysis between solid surfaces linked by a liquid meniscus bridge assuming small vibration of the spacing. As analytical models, the infinite width meniscus, the finite meniscus ring between planes and the finite meniscus ring between a sphere and a plane were considered. It was found that the surface tension of the liquid affects the spring constants and the viscosity of the liquid affects the damping coefficients. The spring constants and the damping coefficients were applied to a mechanical system and the characteristics of vibration transfer through a meniscus bridge were investigated. The effects of the surface tension and the viscosity of the liquid on the amplitude ratio and the phase shift were clarified.
