Description
ригел , при котором в центральном отверстии центрирующей шайбы закрепл ют груз, затем центрирующую щайбу возбул дают акустическими колебани ми и ио измеренным резонансной частоте центрирующей щайбы и массе груза вычисл ют динамическую нодатливость центрирующей шайбы , отличающийс тем, что, с целью повыщени точности измерений, возбуждение центрирующей щайбы нроизвод т цутем воздействи переменного электромагнитного пол на груз, имеющий собственное посто нное магнитное ноле, причем магнитное ноле груза и переменное электромагнитное ноле ориентированы осесимметрпчно между собой и с осью симметрии центрирующей щайбы.A bolt in which the weight is secured in the center hole of the centering washer, then the centering pad of the excitation is given acoustic oscillations and the measured resonant frequency of the centering pad and the weight of the load is calculated by the dynamic vibrations of the centering washer. the centering point is produced by the action of a variable electromagnetic field on the load, which has its own permanent magnetic field, and the magnetic field of the load and the alternating electric Nole osesimmetrpchno gnitnoe oriented among themselves and with the axis of symmetry of the centering schayby.
