Изобретение относитс  к области измерени  параметров движени .The invention relates to the field of motion measurement.

Известные устройства дл  измерени  затухани  механических колебаний стержней круглого сечени , содержащие бесконтактный возбудитель механических колебаний, установленный у консольно закрепленного контролируемого объекта, и емкосгный датчик перемещений , не обеспечивает необходимой точности измерени  из-за вли ни  неупор доченного движени  контролируемого объекта, т. е. нз-за составл ющих изгиба и кручени , при которых плоскость колебаний смещаетс .The known devices for measuring the attenuation of mechanical vibrations of circular rods containing a contactless mechanical vibration exciter installed at a cantilever monitored object and a capacitive displacement sensor do not provide the necessary measurement accuracy due to the influence of an irregular movement of the monitored object, i.e. - for the components of bending and torsion, in which the plane of oscillation is displaced.

В предложенном устройстве емкостный датчик выполнен в виде плоских соосных колец, одно из которых жестко укреплено на торце контролируемого объекта.In the proposed device, the capacitive sensor is made in the form of flat coaxial rings, one of which is rigidly fixed on the end of the controlled object.

Такое выполнение устройства исключает вли ние неупор доченного движени  контролируемого объекта на точность измерени .Such an embodiment of the device eliminates the influence of the disordered movement of the object under test on the measurement accuracy.

На чертеже показапо описываемое устройство , состо щее из бесконтактных возбудителей механических колебаний, например электромагнитных возбудителей 1 и 2, установленных у консольно закрепленного стержн  3 круглого сечени , и емкостного датчика перемещений , выполненного в виде соосных плоских колец 4 и 5, последнее из которых жестко укреплено на торце стержн .The drawing shows the described device consisting of contactless mechanical vibration exciters, for example electromagnetic exciters 1 and 2, installed at a cantilever-mounted circular rod 3 of circular cross section, and a capacitive displacement sensor made in the form of coaxial flat rings 4 and 5, the last of which is rigidly fixed at the end of the rod.

Электромагнитные возбудители 1 и 2 вызывают колебани  контролируемого стержн  на соответственной частоте, амплитуды которых по мере затухани  преобразуютс  емкостным датчиком в электрические сигналы с затухающей амплитудой.Electromagnetic exciters 1 and 2 cause oscillations of the monitored rod at a corresponding frequency, the amplitudes of which are converted by a capacitive sensor into electric signals with a damped amplitude as they decay.

Предмет изобретени Subject invention

Устройство дл  измерени  затухани  механических колебаний стержней круглого сечени , содержащее бесконтактный возбудитель механических колебаний, установленный у консольно закрепленного контролируемого объекта, и емкостный датчик перемещений, отличающеес  тем, что, с целью исключени  вли ни  неупор доченного движени  контролируемого объекта на точность измерени , Б нем емкостный датчик выполнен в виде плоских соосных колец, одно из которых жестко укреплено на торце контролируемого объекта.A device for measuring the attenuation of mechanical vibrations of circular rods containing a contactless mechanical vibration exciter installed at a cantilever monitored object, and a capacitive displacement sensor, characterized in that, in order to eliminate the irregular movement of the monitored object on the measurement accuracy, it uses capacitive the sensor is made in the form of flat coaxial rings, one of which is rigidly fixed on the end of the controlled object.
