LATERAL LOADING BETWEEN LOCOMOTIVE TRUCK WHEELS AND RAIL DUE TO CURVE NEGOTIATION

Curve-negotiation mechanics and forces resulting when locomotive trucks negotiate curves are well recognized. However, meaningful and reasonable prediction of forces resulting in service conditions has been limited. An instrumented wheel-axle assembly was developed and used on 2,3, and 4-axle trucks to study the effect of creep and the transverse load reactions resulting between wheel and rail. Instrumentation was used to measure these forces and the reactions between axles and truck frame under operating conditions. Test results confirm predicted phenomena and indicate the effect of creep on resulting loads. This paper includes a brief and general review of curve-negotiation mechanics and presents the test results and their relation to the theoretical analysis.
