Experimental study on the material selection of the handrail

Abstract

The equipment for measuring the friction coefficient of the skin of palm of the hand was developed. The purpose is to select the material which is optimum for the handrail. There is a case in which the friction changes according to the sliding direction. It is considered that one of the causes is the resistance in which the skin is transformed. Generally, the friction coefficient of which the effect of sliding speed and load is small is measured, when surface roughness of friction material is increased. There may be the relation on the effect of the surface roughness with the sweating of the skin.
