Abstract

It is known that there is not any three-dimensional analytical solution in the analysis of the contact stress for roll-shape member of the limited length. To discuss this kind of questions, the paper presents a method which is known as the photoelastical mixed solution method combined photoelastical technology, Hertz's theory, numerical calculation method and theory of similarity.

Two practical examples in engineering — a working-roll in the mill and a levelling-roll in the levelling machine — have been analyzed here. The analysis results are in complete accord with the phenomenons of the damage of the real components. This denotes that the method presented in the paper is quite reliable.
