J0401-5-4 Development of functional testing equipment measured softness and viscoelasticity

Abstract

The method for examining the surface texture of the flexible thing, namely softness and the viscoelastic property, has not been clearly established. The contactless testing method which could measure the surface texture was proposed, and the development of the functional equipment was tried. It was proposed with the method for measuring the dents using the compressed air. It is possible to display the softness and the viscoelastic property by the method for measuring diameter and depth of the dents.
