Abstract
1. Устройство для диагностики предельного состояния и раннего предупреждения об опасности разрушения материалов и изделий, включающее систему акустико-эмиссионной диагностики, отличающееся тем, что, с целью повышения надежности и точности диагностирования уровня предельных деформаций (напряжений), в наиболее нагруженных зонах конструкции устанавливаются наборы хрупких тензоиндикаторов, настроенные на заданный уровень пороговой деформации меньший или равный предельно допустимой для безопасной эксплуатации конструкции. ! 2. Устройство по п.1, отличающееся тем, что для отделения сигналов образования трещин в хрупком слое тензоиндикаторов от сигналов помех выполняется фильтрация регистрируемых хитов по скорости затухания импульсов. 1. A device for diagnosing the limit state and early warning of the danger of destruction of materials and products, including an acoustic emission diagnostics system, characterized in that, in order to increase the reliability and accuracy of diagnosing the level of ultimate deformations (stresses), sets are installed in the most loaded areas of the structure fragile strain gauges, tuned to a predetermined level of threshold deformation less than or equal to the maximum permissible for safe operation of the structure. ! 2. The device according to claim 1, characterized in that to separate the signals of cracking in the brittle layer of strain gauges from interference signals, the recorded hits are filtered by the pulse decay rate.
