The method for assessing the lifetime of structural elements by the criterion of fatigue strength is improved. It includes tests of laboratory material samples, the positions of the statistical theory of similarity of fatigue failure, calculation of the stress state by the finite elements method and takes into account the nature of cyclic loading with variable amplitude. A way for calculating the...
The fatigue resistance of the cylinder block (CB) of an axial-piston hydraulic machine (APHM) made of tin bronze CuSn12 has been investigated. Fatigue tests of smooth and notched standard samples were performed and fatigue curves were constructed. The stress state of the CB is investigated by the finite element method. It is established that the maximum stresses are localized on a small part of the...
