Claims (1)

Способ акустико-эмиссионного контроля и диагностики резервуаров для хранения сжиженных газов, заключающийся в том, что на объекте контроля устанавливают первичные преобразователи, нагружают объект контроля, регистрируют сигналы акустической эмиссии, по которым судят о техническом состоянии объекта контроля, отличающийся тем, что предварительно проводят исследования акустических свойств и распространения волн напряжения в объекте контроля, по результатам которых регистрация сигналов акустической эмиссии происходит в период времени от начала акта акустической эмиссии до прихода на первичный преобразователь первого ложного импульса (помехи), а обработка сигналов акустической эмиссии продолжается до полного затухания колебаний, вызванных зарегистрированным актом акустической эмиссии, после чего возобновляется регистрация сигналов.The method of acoustic emission monitoring and diagnostics of tanks for storing liquefied gases, which consists in the fact that the primary transducers are installed on the control object, the control object is loaded, acoustic emission signals are recorded, which are used to judge the technical condition of the control object, characterized in that it is preliminarily tested acoustic properties and propagation of voltage waves in the test object, the results of which the registration of acoustic emission signals occurs in a period of time from the beginning of intercourse acoustic emission before the arrival at the transducer of the first false pulse (noise), and the acoustic emission signal processing continues until complete damping of oscillations caused by acoustic emission act registered, then resumes recording of signals.
