Description

39 интервале. Суд т о качестве издели  по параметрам зарегистрированных сигналов акустической эмиссии. Применение данного способа позвол ет исключить вли ние механических и акустически шумов на результаты контрол . Формула нзобретени  Способ контрол  качества изделий из диэлектрических материалов с помощью акустической 3NQiccmi, заключающийс  в том, что нагружают изделие, принимают и регистрирую сигналы акустической эмиссии, по которым суд т о- качестве издели , отличающийс  тем, что, с целью повышени  по мехозащищенности, дополнительно принимают импульсы электромагнитного излучени  от развивающегос  дефекта, задерживают их на врем  распространени  сигнала акустической эмиссии по изделию, а о качестве издели  суд т по сигналам акустической эмиссии при совпадении последних с задержанными импульсами электромагнитного излучени  в заданном временном интервале.

The use of this method eliminates the effect of mechanical and acoustical noise on the control results. Invention Formula A method for controlling the quality of products made of dielectric materials using acoustic 3NQiccmi, which consists in loading the product, receiving and recording acoustic emission signals that judge the quality of the product, characterized in that receive pulses of electromagnetic radiation from a developing defect, delay them for the time of propagation of the acoustic emission signal through the product, and the quality of the product is judged by the signals of acoustic emission and if the latter coincide with the delayed pulses of electromagnetic radiation in a given time interval.
