SEARCH FOR IMPROVED WHEEL MATERIALS

The phenomenon of tread damage as a result of the application of a tread brake has been known for many years and several attempts have been made to develop materials which will resist this damage. In terms of improvements in service performance the traditional methods of simulation dynamometer testing has proved to be unsuccessful. This paper outlines an alternative approach which is based on an understanding of the local fatigue environment in which the tread surface exists. For this approach to be applied successfully certain information must be input concerning the local environment, the relevant mechanical properties and the relationships between them. In this case, the critical location has been taken to be a hot spot. Methods of measuring hot spot temperatures are being developed. However, to identify strains and internal temperatures it is necessary to produce a mathematical model of the hot spot.
