Abstract
Способ определения механических напряжений в рельсах, включающий измерение остаточной намагниченности металла рельсов, образовавшейся в результате эксплуатации рельсовых нитей, отличающийся тем, что над неподготовленной поверхностью каждой рельсовой нити на расстоянии 2-5 мм от их поверхности параллельно друг другу устанавливают сканирующие устройства, с помощью которых измеряют остаточную намагниченность металла рельсов, подключают сканирующие устройства к приемному устройству, установленному на передвигающемся по рельсам приспособлении и содержащем блок питания и цифровой носитель информации с программным обеспечением, переводят с помощью программного обеспечения получаемые при перемещении сканирующих устройств данные остаточной намагниченности в данные механических напряжений в рельсах, фиксируют полученные результаты как в реальном времени, так и накапливают в блоке памяти.A method for determining mechanical stresses in rails, including measuring the residual magnetization of the metal of the rails formed as a result of the operation of rail threads, characterized in that scanning devices are installed parallel to each other over the unprepared surface of each rail thread at a distance of 2-5 mm from them, by which measure the residual magnetization of the metal of the rails, connect the scanning devices to the receiving device mounted on the moving rails and containing in autonomous power supply and digital information carrier with software converted using software obtained while moving the scanning device data into the data remanence mechanical stresses in the rails, fixed results in real time, and store in the memory unit.
