Abstract

The fatigue performances of two types of the automotive frame steel (AFS) include WL700 and WL510 are investigated. In order to take the thickness effect into account, two series of WL510 samples with 6mm and 8mm thickness respectively are selected. The fatigue strengths are calculated by one and two dimensional up-and-down method under dfifferent probability of failure and believe. The result shows that the relative deviation of fatigue strength using one dimensional method is much 3 to 4 times larger than two dimensional method. In addition, more experienced data brings more accurate result. The relative deviation of fatigue strengths become larger, when the probability of failure increased and probability of believe decreased.
