Energy Technologies & Resource Saving| Summary: | The subject of research of this paper is the analysis of the stress-strain state of a stay ring/spiral case system of Francis turbine РО400-B-450 as not concreted and comparison between the results obtained and experimental data. The set of studies conducted allowed detecting of the fields of displacements and stress intensity as well as more accurate defining of the principal stresses distribution and zones of maximum stress localization. The comparison results showed that the method used ensured a good agreement with the data of field research, this allowing a qualitative evaluation of the stress-strain state of еру stay ring/spiral case assembly. |
