Abstract

Изобретение относитс  к измерительной технике, а именно к способам контрол  трещинообразовани . Цель изобретени  - повышение надежности измерений путем обеспечени  возможности определени  координаты трещины при замыкании на конструкцию 1 разрывающейс , электроизолированно приклеенной к конструкции фольги 3. Дл  этого измер ют врем  запаздьшани  отраженного импульса при поочередном возбуждении измерительного импульса на концах 4 и 5 фольги 3. 1 ил. с This invention relates to a measurement technique, in particular, to methods for controlling crack formation. The purpose of the invention is to increase the reliability of measurements by making it possible to determine the coordinate of a crack when a short circuit is interrupted on the structure 1 of the foil 3 that is electrically adhered to the structure. with

Способ определения координаты трещины при испытаниях металлических конструкций, заключающийся в том, что на исследуемую конструкцию неэлектропрсводным клеем наклеивают металлическую фольгу при нагружении конструкции до образования трещины, поочередно возбуждают электрические импульсы с разных концов фольги и . измеряют электрические параметры системы фольга - конструкция, по которым определяют координату трещин, отличающийся тем, что, с целью повышения надежности измерений путем обеспечения возможности определения координаты трещины при замыкании разрывающейся фольги на конструкцию, в качестве электрических параметров используют интервалы времени между приходами измерительного и отраженного импульсов на соответствующий конец фольги.A method for determining the coordinates of cracks during testing of metal structures, which consists in the fact that a metal foil is glued onto the test structure with a non-electrically conductive adhesive when the structure is loaded until a crack is formed, and electrical pulses are alternately excited from different ends of the foil and. measure the electrical parameters of the foil system - design, which determine the coordinate of the cracks, characterized in that, in order to increase the reliability of measurements by providing the ability to determine the coordinates of the cracks when a tearing foil is closed to the structure, the time intervals between arrivals of the measuring and reflected pulses are used as electrical parameters to the corresponding end of the foil.
