METHOD FOR EXAMINING AUTOMOBILE TYRES Russian patent published in 2022 - IPC G01M17/02 G01H9/00 

FIELD: tyres.

SUBSTANCE: invention relates to the tyre industry, in particular, to methods for examining automobile tyres, including large-size tyres (LST) of machines used in mining and building. The method involves the use of powerful broadband ultrasonic pulses generated by a pulse-periodic laser, transmitted to the examined tyre through an optically transparent waveguide in contact therewith, and reception of signals reflected from the structural elements of the examined tyre by a piezo receiver. The emission of ultrasonic pulses and the reception of signals reflected from the internal elements of the tyre are therein executed consecutively through blocks arranged in a single row, including an acoustic waveguide and a piezo receiver, and the group formed therein moves in a spiral the axis whereof coincides with the axis of rotation of the examined tyre.

EFFECT: increase in the accuracy, speed and security of identifying hidden defects of a tyre and ensured informed decision-making on the practicability of restoration thereof.
