Бесконтактный экспресс-контроль взаимного положения рельсов железнодорожной колеи

Abstract

In article the device of the control of linear vertical, linear cross-section horizontal and angular movings, and also width of top of a head of a rail is considered. Matrix configuration and inphase excitation eddy current the converters is offered, allowing to create the common electromagnetic field providing the control over a wide range of change of geometrical parameters. The technique of recognition of an electromagnetic image of a rail is based on selection of controllable factors by means of digital processing measuring signals.

В работе рассмотрено устройство контроля линейного вертикального, линейного поперечного горизонтального и углового перемещений, а также ширины верха головки рельса. Предложены матричная компоновка и синфазное возбуждение вихретоковых преобразователей, позволяющие создать общее электромагнитное поле, обеспечивающее контроль в широком диапазоне изменения геометрических параметров. Методика распознавания электромагнитного образа рельса основана на селекции контролируемых факторов с помощью цифровой обработки измерительных сигналов.
