Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 The quality of calculations of the stress state of the thrust bearing of the hydrogenerator of Art. №2 Middle Dnieper HPP with defects of the mirror surface regarding the possibility of its long-term operation. The calculations were performed by the Customer on a modern software package SolidWorks (Simulation package), for the use of which the Customer has a license. Formation of a three-dimensional computer model of a disk of a thrust bearing of the hydrogenerator of Art. №2 Middle Dnieper HPP with defects of the mirror surface in the software complex SolidWorks was performed according to the drawing BILT.301319.224SB and the results of color flaw detection. During the preparation of the initial data and during the processing of the results of the calculation of the stress state of the thrust disk defects in the Simulation software package, modern scientific approaches and generally accepted methods were used. The method of calculations and the materials submitted for examination indicate that they were performed at the appropriate quality level. Expert analysis of the results of calculations on models created using the results of color flaw detection, allows us to draw conclusions about the impossibility of long-term operation of the thrust disk of the hydrogenerator. №2 Middle Dnieper HPP with existing defects of the mirror surface.
