Abstract
In optimization process of crane structures the high level of material exploitation is often requested, which results in lower costs and suitable safety of operating construction. Expected goals should be achieved using quality high-strength steels, like S960QL and S1100QL. Crane structures are exposed to the time depending loading at operational stage. Therefore, the evaluation of service life of crane structures, manufactured from new and quality steels, is important and complex task. The proposed research is based on logical combination of experimental and analytical-computational approaches for determination of the fatigue service life of crane structures. The research is focused on experimental determination of main material parameters, required for description of fatigue process and development of suitable numerical models for usage in the engineering practice. Numerical simulation will be based on finite element method (FEM) and fatigue strength calculation analysis, like S-N, e-N and SWT methods. For verification of developed models a comparison with already performed measurements of service life for certain crane elements will be performed.
