摘要
The article considers a problem of identifying and adjusting erosion-fatigue properties of materials used for manufacture of wet-steam turbine blades and protective coatings for them. Here the authors offer the inverse problem solution algorithm to predict an erosion wear allowing to identify erosion-fatigue properties. It is based on computer simulation of erosion caused by high-cycle material fatigue as a result of numerous drop impacts on the surface of wet-steam turbine blades. Determination of optimum erosion-fatigue material properties relies on the method of direct search with constraints and the results of observation of full size turbine blade erosion areas are used as the source data. The possibilities of software package "Erosion" in solving this problem are described. There are given the results of computational experiments to identify erosion-fatigue material properties of turbine blades K-300-240 of the Leningradskiy Metal Plant and main turbine set of atomic icebreaker "Lenin". The estimation of accuracy and adequacy of the results of computational experiments identifies erosion-fatigue material properties and protective coatings.
