Документ Исследование вибронагруженности элементов тележек электропоезда ЭПЛ-9Т(НТУ "ХПИ", 2007) Яцько, С. И.; Карпенко, В. В.; Ковалев, А. Е.The questions of definition the vibration load in conditions the ordinary of maintenance of elements of a running part of an electrotrain EPL-9T, manufacture company «Luganskteplovoz» are considered. The dependences of peak and average quadratic values vibration of acceleration, frame of the carriage, bearing assembly and of the electric motor from speed of driving of an electrotrain are obtained. The estimation of influence of electromagnetic perturbations of a drive on results of measurements is given. The obtained datas will be used in designer practice at projection new and operational development of serial elements of a running part of an electrotrain.Документ Виброизмерения рам тележек вагонов метрополитена в эксплуатационных условиях(НТУ "ХПИ", 2007) Жовдак, В. А.; Белоцерковский, Александр Борисович; Смирнов, М. М.; Ульянов, Юрий Николаевич; Яцько, С. И.; Черных, О. В.The article represents the vibration-survey technique of bogie frames of transit vehicles under service conditions. The oscillogram processing was carried out by discrete Fourier transform. For this purpose program Microsoft Excel was used. The spectrum of external loading is defined. This loading is caused by track irregularities. Also the natural vibration spectrum of bogie frames is obtained and confirmed by experimental data. The results of this article will be used for solving the statistical dynamics problem and reliability prediction of bogie frames. The delay of external loading on the weel pairs of bogie frames is taken into account.
