Abstract

A series of fatigue tests on railway bogie (undercarriage) components has been completed in Finland and Sweden. Tests were designed to evaluate the high cycle fatigue behavior of welded constructions. The loading was based on in-service field measured data. A standard test procedure for evaluating the fatigue integrity of bogies is based on an assumption of infinite life and in-phase interaction between four load actuators. The relationship between the standardized loads and the actual field service loadings is examined. Results showed that design and testing procedures should be based on a long but finite life concept that recognizes the large amount of fatigue damage that can be contributed by small cycles in a spectrum that contains only a small portion of large cycles that exceed the constant amplitude fatigue limit.
