Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

During development of algorithms for vibration diagnostic systems, special attention is given to studying the main types of rolling equipment, vibration characteristics are determined, and features of the influence of metal rolling technology on the technical condition of the equipment are taken into account. As a result of the conducted examination and analysis of vibraiton parameters of stands of medium section А/С 400/215 and flatting NTLS-1680 rolling mills, a variant of mounting vibration sensors in the vertical direction along the main line of the drive was selected. This variant of accelerometer orientation ensured maximum informativeness of the system during diagnostics of rolling equipment. A design feature of turning stands of medium section mill is the availability of angular gearbox. Here, the sensors mounted on the bearings of the input and output shafts, are located orthogonally relative to each other. Synchronous recording of vibration signals by a measuring module of “Corundum” system allowed revealing certain regularities in the operation of bevel gear in the angular gearbox of the stand. Combining on the software level the temporary signals read from paired sensors resulted in plotting the hodographs of spatial position of reference points of the engaged shafts. The proposed method of visualization allows assessment of the technical condition of the angular gearbox of the stand, in addition to hte available algorithms realized in vibration diagnostics system.
