Metoda symulacji złożonych obciążeń stochastycznych w badaniach zmęczeniowych elementów

A method is presented of programming tests of fatigue elements of the mechanical systems, exposed to the action of complex service loads. The suggested method of approximation of random fatigue loads, refers to the cases when one of the random functions, has a negligible changing frequency in comparison to the other. A construction of a supplementary block of harmonic loadings, which, under accelerated tests, corresponds to a certain period of exploitation of the object, has been presented in the paper. The method has been illustrated by an example of the durability of an articulated shaft of car steering wheel.
