Okhrimenko K. Methods and applications of computer modelling of oscillatory processes rotor systems.

Dissertation research is dedicated to decision of the actual research problem ? the developments of the mathematical models complex of the oscillatory processes the most wide-spread type of the rotor systems, which allow to improve the methods and applications of computer modeling for the reason efficient organization of the studies, test and vibrodiagnostics, as well as increasing to reliability of the rotor system work. Mathematical models, which are used for preparing the raw data of the development process of the dynamic models and descriptions of the dynamic processes rotor miscellaneous type, As well as methods of the processing information array, which get, executing vibrodiagnostics and estimation of inaccuracy cylindrical and cone-shaped surfaces, in particular, at analysis running track rings bearing swings with use the quick transformations Fourier and decompositions in row on Walsh-Hadamard, Walsh-Pely, and Walsh-Kachmazh orthogonal transformations system are created and advanced.
