Abstract An examination is made of the method of evaluating the reliability of a restored object in failures of elements due to fatigue. The evaluation method is based on simulating the fatigue failure process taking into account its two-stage form, the repair cycle of the object, and crack diagnostics. It is proposed to simulate the working life to the appearance of a fatigue crack by the corrected Serensen-Kogaev linear model of damage cumulation, and simulate the life on the basis of models, constructed using a special multifactor of experiment, which reflect the effect of significant service factors on the crack growth rate. An algorithm of modeling two types of failures of a restored object using the method of statistical testing is proposed. The reliability of a freight-car is evaluated on the basis of failures of a coupler yoke of the automatic coupling device.
