Measurement of the Complex Compliance of Coatings of Elastic Materials

Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

A procedure for measuring the compliance of viscoelastic coatings that are used to reduce the hydrodynamic friction has been developed (the frequency range of measurements is from 400 Hz to 2 kHz). The set of force transducers differing by the diameter of the surface of contact with a coating has been manufactured. The frequency and amplitude characteristics of the transducers have been given. It has been shown that the dynamic compliance is independent of the static deformation ε if ε >3%. The diameter of the coating sample for which the edge effects are of little importance has been selected. It has been shown that with a twofold increase in the coating thickness the measured resonant frequency of the coating decreases twofold as well.
