Podgorny's Institute of Mechanical Engeneering Problems of the National Academy of Science of Ukraine popup.description2 This work analyzes the current state of vibrations turbomachinery blading with damages, and summarized the experience of exploitation of the blades of titanium alloys with erosional damages, and the results of previous studies of changes in the structure of the material in cases of damage. On the basis of these investigations determined the requirements for the studied process models. The three-dimensional models of vibration of the blades and impellers with erosional damages with taking into account of operating conditions are developed. The test calculations of vibrations blades with erosional damages and of impellers turbines for nuclear power plants were conducted Product Description popup.authors Воробйов Юрій Сергійович Депарма Галина Олексіївна Кулаков Петро Миколайович Овчарова Наталія Юріівна Ткачик Олена Миколаївна popup.nrat_date 2020-04-02 Close
