Документ Расчет колебаний и ресурса трубопровода маслосистемы газоперекачивающего агрегата(НТУ "ХПИ", 2001) Белоцерковский, Александр Борисович; Жовдак, В. А.; Левашов, В. А.; Трубаев, Александр ИвановичThe average time before fracture due to fatigue damage accumulation in spatial piping systems under kinematical excitation is determined. It is supposed that all supports of the piping system subjected to the identical acceleration modeling stationary random process. The solution of this problem is based on the finite element method and the spectral method. The computer program for IBM PC on the basis of this algorithm has been developed.Документ Статистический анализ и собственные колебания рабочего колеса турбокомпрессора с учетом технологических погрешностей(НТУ "ХПИ", 2001) Жовдак, В. А.; Смирнова, Л. М.The static stress-and-strain state and free vibrations of cyclic symmetry structure with mistiming are investigated. The paper deals with the process misnming modeling one variant on the 3D-model of the centrifugal turbocompressor firststage wheel. Comparative results of tuned and mistimed system analysis are presented.
