CONSTRUCTION OF A MATHEMATICAL MODEL OF A DEFECT IN THE APPEARANCE OF AN INTERNAL CRACK IN A TURBINE OR PUMP BLADE

Abstract

The appearance of a crack in the turbine or pump blade with the subsequent occurrence of vibration is considered. Dependences for determining the presence of a defect and the level of vibration are obtained, and phase portraits of vibrations based on the obtained dependences are constructed. The result of the study is the possibility of simulating the defect on relatively simple mathematical models.
