The purpose of the work was development of mathematical models, approximate methods for dynamic processes research in mechanical systems under the action of complex loads. Research methods were numerical-analytical. An efficient mathematical tools were worked out to solve the problems of durability in mechanical systems under the action of complex loads. The behavior of elastic-plastic waves under complex loading was researched. The method for modeling of wave processes, based on a grid-characteristic approach was improved accounting complex loads. The effect of moving loading on reinforced end edges of the cylindrical shell was investigated using the method of characteristics, which enabled to take into account the discontinuities of stress and deformation at the points of application of the moving forces and on the fronts of waves of compression and shear, to identify resonant oscillations provided matches the rate of displacement forces with one of the wave speeds. The problem of propagation of longitudinal-transverse waves in an elastic-plastic half-space for loads that vary in time was solved. A bench was designed to diagnose vibrations of thin-walled parts such as blades of blisk GTE in end milling. Analytical and numerical studies of the stress-strain state of a number of concrete constructions under complex loads were performed. The software package was developed. The results could be used in engineering. Product Description popup.authors Анпілогов Д.І. Коротунова О.В. Левада В.С. Левицька Т.І. Мізерна О.Л. Нечипоренко Н.О. Пожуєва І.С. Шишканова Г.А.
