Abstract

The aim of this paper is to introduce an accelerated test model in fatigue life reliability analysis dealing with variation in material properties. Service loads in terms of response-time history signal of Belgian pave were replicated on a multi-axial spindle coupled road simulator and stress-life method was used to estimate the fatigue life of automotive stub axle. A probabilistic stress-life (PSN) curve was obtained by cyclic tension test and inverse power law stress-life model with lognormal distribution function was used to acquire the mean life of the component. A Pearson system was developed to evaluate the fatigue life reliability by considering stress range intercept and slope of the PSN curve as random variables. Considering normal distribution of fatigue strength, it is found that the fatigue life of the stub axle to have the highest reliability between 4000-5000 cycles. Taking into account the variation of material properties associated with the size effect, machining and manufacturing conditions, the method described in this study can be effectively applied in determination of probability of failure of mass-produced parts.
