Abstract

Fatigue life determination of vehicle parts requires fine definition of load spectra applied. Significant load spectra must be defined from experimental data. Then, using Gram-Charlier-Edgeworth mathematical developments, global shapes of loading distribution curves are obtained. In addition to considering the physical aspect of material fatigue behaviour, a local definition of extreme loading is introduced. Frequency analyses are linked to the distribution of amplitudes. 200 practical recordings are analysed. Equivalent load spectra are compared to S-N curves and correlations between real loading of vehicle parts in service and laboratory test loading are obtained.
