Abstract:

The paper is the result of the cooperation between WSK Rzeszów company and the AGH within SPAW project. In the paper thermo-mechanical analysis of the power turbine casing for a PZL-10W engine at the running conditions was considered. The goal of the work was evaluation of possibility of prediction of the thermal fatigue in the casing using numerical calculations carried out with commercial software Morfeo, based on the finite element method combined with the material fatigue models. Conventional fatigue models presented in the literature, dedicated to low cycle material fatigue, were implemented as the external procedures to Morfeo, compatible with the interface output data set format. Thermomechanical parameters calculated by the FE program are an input for the fatigue model. The results of the calculations were compared to the results observed in the real casing at the running conditions. The quantitative agreement was approved.
