Документ К активному гашению колебаний упругих систем(НТУ "ХПИ", 2006) Галас, Олег Сергеевич; Аврамов, К. В.Method of the active damping of beam oscillations is proposed in this work. Essentially nonlinear absorber with the feedback is attached to the beam. Method of the harmonic balance is used to investigate the system with the active absorber. Analysis of system stability is performed. Amplitude-frequency characteristic of the beam and absorber is buildДокумент Нелинейные свободные колебания закрученных вращающихся стержней(НТУ "ХПИ", 2006) Аврамов, К. В.; Ширяева, Наталья Владимировна; Ищук, Ю. А.; Розова, Людмила ВикторовнаThe system of three partial differential equations describing flexural-flexural-torsional vibrations of pretwisted beam is introduced in this paper. An assumption that the center of gravity and the shear center are in different points is used here. Nonlinear modal analysis is used for discretization of this system. Free nonlinear oscillations are investigated by Shaw-Pierre methodДокумент Устойчивость нелинейных форм вынужденных колебаний в дискретной системе с кубической нелинейностью(НТУ "ХПИ", 2006) Бреславский, И. Д.; Аврамов, К. В.The nonlinear normal modes of the system with cubic nonlinearity are studied. The variation equations are used to study stability
