Description
CS) УСТРОЙСТВО дл НЕРАЗРУШАЮЩЕГО КОНТРОЛЯ МЕТОДОМ АКУСТИЧЕСКОЙ ЭМИССИИCS) DEVICE FOR NON-DESTRUCTIVE MONITORING BY THE ACOUSTIC EMISSION METHOD
II
Изобретение относитс к неразрушающему контролю и может быть ис- , пользовано дл контрол дефектовизделий по сигналам акустической эмиссии .The invention relates to non-destructive testing and can be used to control product defects by acoustic emission signals.
Известно устройство, содержащее соединенные последовательно преобразователь ,предусилитель, усилитель, амплитудный дискриминатор, интенсиметр и регистрирующее устройствоCI.A device comprising a converter, a preamplifier, an amplifier, an amplitude discriminator, an intensity meter and a recording device C1 connected in series is known.
Наиболее близким по технической сущности к изобретению вл етс устройство дл неразрушающего контрол методом акустической эмиссии содержащее последовательно соединенные преобразователь, предусилитель, усилитель и не менее трех параллельных каналов, каждый из которых состоит из последовательно соединенных дискриминатора, формировател и интенсиметра, а также регистраTopJU . ....The closest in technical essence to the invention is a device for non-destructive acoustic emission monitoring containing a series-connected transducer, a preamplifier, an amplifier and at least three parallel channels, each of which consists of a serially connected discriminator, a former and an intensimeter, as well as a TopJu register. ....
Недостатком этих устройств вл етс мала точность контрол , обусловленна низкой информативностью параметров сигналов акустической эмиссии, не позво 1 ющих определ ть относительную эмиссионную активность сигналов с различными амплитудами, что затрудн ет оценку накоплени повреждений в материале при испытани х конструкций.The disadvantage of these devices is the low control accuracy due to the low information content of the parameters of acoustic emission signals, which do not allow determining the relative emission activity of signals with different amplitudes, which makes it difficult to estimate the damage accumulation in the material during structural tests.
Цель изобретени - повышение точности контрол .The purpose of the invention is to improve the accuracy of control.
