Ermittlung des Längsschlupfes eines angetriebenen Kranrads bei bombiertem Schienenkopf

Abstract

The longitudinal creep on a crane wheel has considerable effects, both for the design and the control of the drive technology of a modern crane. The creep values occurring during operation are, however, widely unknown. This article presents a calculation model for longitudinal creep of a driven crane wheel, which can be used for a fast analytical determination. Based on the contact area between the crane wheel and the rail, instead of the complex real point contact situation an equivalent line contact is calculated. The approach was validated at the Institute's wheel-rail test rig.
