METHOD FOR DETERMINING THE OPERABILITY OF THE TRANSDUCER OF SPATIAL VIBRATION ON A WORKING OBJECT Russian patent published in 2022 - IPC G01H11/08 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology. The spatial vibration transducer is installed on the object and its channels are connected in accordance with the operating instructions to power sources and an analog-to-digital converter, and the latter is connected to a personal computer with a pre-installed information processing program. The transducer of spatial vibration is affected by the vibration of the operating object and signals are received at the outputs of the channels, which are measured and stored in one orthogonal and three oblique spatial coordinate systems. After bringing the values ​​of the projections of the spatial vibration vector of the object in three oblique coordinate systems to the values ​​of their projections in the orthogonal system, four values ​​of the module of the vibration vector are determined in each of the spatial coordinate systems, the arithmetic mean value and the deviation of the module values ​​of the spatial vibration vector from the arithmetic mean value. Comparison with a predetermined maximum permissible deviation preliminarily determines the performance of the transducer of spatial vibration on a working object. Then the relative differences between the arithmetic mean value of the spatial vibration vector and the measured absolute values ​​of the projections of the spatial vibration vector on the orthogonal sensitivity axes of the transducer are determined, compared with the given first additional limit value of the relative differences, the comparison results are used to determine the projections of the spatial vibration vector on the orthogonal sensitivity axes with small values, after that, the absolute relative deviations of the calculated values ​​of orthogonal projections from their measured values ​​are determined, these deviations are compared with the given second additional limit deviation value, the serviceability of channels with small values ​​of orthogonal projections is determined, and the final conclusion is made about the operability of the spatial vibration transducer.

EFFECT: possibility of obtaining objective information about the state of operation of the converter.
