| Abstract | Load spectrum plays a pivotal role for fault diagnosis and reliability evaluation. Here we performed long-term field tests to investigate the characteristics of load spectra of the bogie frame in a high-speed train. With increasing steps of classifications, we reveal an apparent segmented feature of the load spectrum. We propose a new theoretical model, a segmented Weibull distribution, to describe this new characteristic. Contrast to existing models, the inflection stress in our segmented Weibull model can be employed to describe the quality of lines, and the directly parameterization for the load spectrum - line quality relationship is hardly seen in existing literature. These findings reported here are in generally applicable to other dynamic systems where fatigue failure is of paramount importance. |
