CAD APPROACH FOR PROFILE OPTIMIZATION OF RAILWAY WHEEL THREAD

This paper describes design concepts, process, and test results of a newly developed computer aided design (CAD) approach for optimization of railway wheel tread profile. This approach consists of a 3-dimensional geometric analysis and linear/nonlinear vehicle dynamic analyses. It can achieve a satisfactory solution for the requirements of hunting stability, curving performance, wheel/rail wear reduction, and safety against derailment, some of which conflict each other. The profiled wheels designed by using the CAD approach have proved to have sufficient performance in laboratory and field tests, which provides such strong confirmation that this approach is satisfactory as a useful design tool.
