Information × Registration Number 0209U005629, 0107U009499 , R & D reports Title Diagnostics of the vibration and stressed state, and assessing turbine rotor crack growth life. popup.stage_title Head Efremov Yu.G., Registration Date 12-03-2009 Organization A.Podgorny Institute for Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 The method and the software for crack detection in a rotor by vibratory signature are created. The joint solution technique of three-dimensional non-stationary heat conductivity and thermal mechanics problems is developed for non-uniform body of rotation. Computational investigation results of T-250/300 turbine rotor service life at presence of a crack in area of flushing hole boring and in a ground part of thermal groove and the deflected mode of high-temperature rotors taking into account the circumferential non-uniformity of material creep properties are obtained. Application - power machine building. Product Description popup.authors popup.nrat_date 2020-04-02 Close
