PENDULUM CALIBRATION VIBROBENCH Russian patent published in 2021 - IPC G01M7/00 

FIELD: measurement technology.

SUBSTANCE: invention relates to measurement technology, namely to devices for measuring the parameters of vector objects in the low-frequency range, and can be used in geophysics to study such parameters as sensitivity, directional characteristic and the division coefficient of the directional characteristic of acceleration channels, in particular, vector type receivers and their elements, as well as for use in the technological cycles of manufacturing accelerometers for selecting sensors by sensitivity. The vibrobench contains a base, a swinging unit with a device for placing the object under study, an electronic unit, a swing angle sensor, a multi-channel amplifier, an ADC and a digital communication system. In addition, it also contains a processor unit connected to an electromagnet, a permanent magnet mounted on the cheek of the swinging unit, as well as a swing amplitude setter and an indicator of acceleration, frequency and swing amplitude connected to the processor unit.

EFFECT: simplification of the technology of use, the increase of accuracy in measurements, as well as simplification of processing the results obtained.
