A RESEARCH OF FATIGUE IN RESILIENT WHEELS OF WHEELSETS FOR METRO WAGONS
Dobrinka Borisova Atmadzhova The elastic wheels of metro wagon type 81-717.4 and 81-714.4 in Sofia have metal and elastic elements. It has been established that the average lifecycle of the elastic-type metal-rubber bundles in operating conditions does not exceed 55% of the producers” guaranteed life cycle. Finite element analysis has been used to predict stress distributions and evaluate the fatigue behavior. Nonlinear quasi-static analysis is performed taking into account the residual stresses to obtain the effective range of stresses and predicting the occurrence of metal cracks.
