METHOD AND DEVICE OF CONTROL OF DYNAMIC CONDITION OF INTERACTION OF LOCOMOTIVE ENGINE ELEMENTS Russian patent published in 2019 - IPC G01H9/00 G01M17/08 

FIELD: measurement.

SUBSTANCE: invention relates to measurement technology and can be used to determine the reliability of the windings of an electric motor of a locomotive. Method of controlling the dynamic state of the forms and interaction features of the elements of an electric locomotive engine consists in fixing a measuring device to the engine to control its dynamic state, consisting of a sensor for detecting the appearance of a gap between the inertial element and the hole in the lower part of the body and the information processing unit. Sensor consists of a housing, in the central part of which a tube is located, to which an optical fiber light guide is attached, connected to the information processing unit. Information processing unit consists of a comparator, powered by an energy source, a converter and a counter. Energy source feeds the comparator, the counter and the light source connected to the lower light guide. Through the hole in the lower part of the body, the light flux from the lower light guide passes through the annular gap, is reflected on the walls of the body and enters the upper light guide, from where the pulse is sent to the comparator, which compares the signal with the lower norm of unwanted noise, the signal from the comparator is fed to the converter, which sends it to the counter, fixing the number of shock interactions of engine elements, which is compared with the limit value of the cycles of dynamic loading.

EFFECT: technical result is to minimize the influence of fields of electromagnetic nature when monitoring the dynamic state of the engine.
