FIELD: measurement equipment.SUBSTANCE: bench comprises a suspension, a chamber with the possibility to fix the gyromotor by equatorial or polar axes along the vertical axis of the suspension, the first and second magnetoelectric sensors installed coaxially in the bench body, a measurement amplifier, a power amplifier, the load of which is a winding of the second sensor, and current leads, opposite ends of which are connected via contact circuit boards to the chamber and the body. At the same time the winding of the first sensor is connected via the measurement amplifier with a facility of signal measurement, the suspension is connected to the chamber and is installed in bearings of the body, current leads are made in the form of springs with the possibility to change stiffness ratio. Additionally the structure includes a narrowband filter, by the output connected to the input of the power amplifier, and by the input connected to the output of the measurement amplifier, at the same time the filter provides for amplification or suppression of a separate harmonic of the signal from the output of the measurement amplifier.EFFECT: increased accuracy of gyromotor vibration monitoring.4 dwg |
