Изобретение относитс к контрс лю напр жений в издели х из ферромагнитных материалов и может быть использовано на предпри ти х машиностроительной , транспортной и авиационной промышленности дл объектов, имеющих вращающиес части.The invention relates to stress stresses in products made from ferromagnetic materials and can be used in enterprises of the machine-building, transport and aviation industries for objects with rotating parts.
Известен способ магнитошумового контрол напр жений в механизмах, включающий замыкание магнитопровода ю датчика участком детали контролируемого механизма и перемагничивание детали по предельной петле гистерезиса . Формируют текущий спектр магнитных шумов, а качество детали оп- is рёдел ют по форме нормированного спектра относительно одной из его составл ющих 1 .There is a known method of magnetic noise control of stresses in the mechanisms, including the closure of the sensor magnetic circuit by the part of the controlled mechanism and the remagnetization of the part along the limiting hysteresis loop. The current spectrum of magnetic noise is formed, and the quality of the part is determined in the form of the normalized spectrum relative to one of its components 1.
Недостатком известного способа вл етс его низка точность при контроле состо ни механизмов в процессе их работы.The disadvantage of this method is its low accuracy in monitoring the state of the mechanisms during their operation.
Цель изобретени ,- повышение томности .The purpose of the invention is to increase the languor.
Цель достигаетс тем, что согласно способу магнитошумового контрол , напр жений в механизмах,включающему замыкание участка детали контролируемого механизма магнитопроводом датчика , перемагничивание детали по предельной петле гистерезиса и формирование текущего спектра магнитных шумов, частоту перемагничивани детали устанавливают равной частоте вращени ведущего вала контролируемого механизма, выдел ют максимальное значение огибающей текущего спектра магнитных шумов , поворачивают датчик вокруг его вертикальной оси на ЗбО°, определ ют зависимость выходного сигнала от угла поворота, при этом контроль ведут по направлению оси чувствительности датчика в момент времени, соответствующий равенству нулю первой производной выходного сигнала по углу поворота .The goal is achieved by the fact that, according to the method of magnetic noise control, stresses in the mechanisms, including closure of the part of the controlled mechanism by the sensor magnetic circuit, reversal of the part through the limiting hysteresis loop and formation of the current magnetic noise spectrum, the frequency of the reversal of the part of the monitored mechanism, the maximum envelope value of the current spectrum of magnetic noise is applied, the sensor is turned around its vertical axis to 30%. Was determined from the dependence of the output steering angle control are thus axially sensor sensitivity in a time corresponding to the vanishing of the first derivative of the output signal of the rotation angle.
Способ магнитошумового контрол напр жений осуществл етс с помощью шиThe method of magnetic noise voltage control is carried out using shea
