Abstract
Способ диагностики поверхности катания колесных пар подвижного состава железнодорожного транспорта и метрополитена, заключающийся в измерении сигналов акустической эмиссии вращающейся колесной пары и отличающийся тем, что датчики (преобразователи) акустической эмиссии не менее двух устанавливают на любую поверхность правового и левого рельса, кроме поверхности головки рельса железнодорожного пути по оси, перпендикулярной направлению железнодорожного пути, и во время прохождения подвижного состава определяют с частотой выборки от 50 до 0,1 мкс значение выброса максимальных амплитуд сигналов акустической эмиссии следующих последовательно и неразрывно по времени, определяют время длительности выброса максимальных, последовательных и неразрывных по времени сигналов акустической эмиссии Δt и интервалы времени от начала периода вращения колесной пары до первого и последующих выбросов максимальных, неразрывных по времени сигналов акустической эмиссии в течении периода (времени одного оборота) и рассчитывают размер дефекта вдоль беговой дорожки в мм по формуле ! P=π·D·n·∆t, ! где Р - размер дефекта в мм, ! n - число оборотов в с, ! ∆t - время длительности выброса сигналов акустической эмиссии с максимальной амплитудой следующих один за другим неразрывно по времени в с, ! π-3,14, ! D диаметр колеса вагона или локомотива до поверхности катания в мм, ! о состоянии поверхности катания колесной пары судят путем сравнения определенного диагностикой размера дефекта такого типа и их количества, исходя из технических и эксплуатационных характеристик колесной пары. A method for diagnosing a rolling surface of wheel pairs of rolling stock of a railway transport and a subway, which consists in measuring acoustic emission signals of a rotating wheel pair and characterized in that the acoustic emission sensors (transducers) of at least two are installed on any surface of a right and left rail, except for the surface of a rail head of a railway the path along the axis perpendicular to the direction of the railway track, and during the passage of rolling stock is determined with a sampling frequency of 50 to 0.1 μs the value of the emission of the maximum amplitudes of the acoustic emission signals following sequentially and inextricably in time, determine the duration of the duration of the emission of the maximum, sequential and time-continuous acoustic emission signals Δt and the time intervals from the beginning of the period of rotation of the wheelset to the first and subsequent maximum emissions , time-continuous acoustic emission signals during the period (time of one revolution) and calculate the size of the defect along the treadmill in mm according to the formula! P = π · D · n · ∆t,! where P is the defect size in mm,! n is the number of revolutions in s,! ∆t is the time duration of the emission of acoustic emission signals with a maximum amplitude following one after another inextricably in time in s,! π-3,14,! D The diameter of the wheel of the car or locomotive to the rolling surface in mm,! the state of the wheelset’s rolling surface is judged by comparing the size of the defect of this type determined by the diagnostics and their quantity, based on the technical and operational characteristics of the wheelset.
