Изобретение касаетс испытательной техники, а именно способов определени прочностных свойств материалов.The invention relates to test equipment, namely methods for determining the strength properties of materials.
Известен способ неразрушающего ксег рол прочностных свойств материала, заклврчающийс в том, что изделие подвергают механическому нагружению, наклеивают тензодатчики , по интенсивности сигнала которых суд т о действующих напр жени х,при достижении критических значений которых нагружение прекращают f 1.A known method for non-destructive material strength properties, which means that the product is subjected to mechanical loading, is glued to strain gauges, the signal strength of which determines active stresses, at which critical values are reached, loading stops f 1.
Однако необходимость контакта тензодатчика с изделием вносит погрещность в результаты испытаний, которые обуславливаютс надежностью креплени тензодатчи (КОВ и вли нием вибраций.However, the need for contact of the strain gauge with the product introduces a gap in the test results, which are caused by the reliability of fixing the strain gauge (COB and the effect of vibrations).
Известен способ испытани изделий на прочность, заключающийс в том, что изде лиё подвергают механическому нагружению в месте возможног-о возникновени трещин размещают детектор электронов и регистригруют эмиссгао электронов с поверхности из дели , по которой суд т о прочностных свойствах издели 2 .The known method of testing products for strength is that the product is subjected to mechanical loading in the place of possible cracking, the detector of electrons is placed and the emission of electrons from the surface of the product is recorded, according to which the strength properties of the product 2 are judged.
Однако дл этого способа характерна However, for this method is characteristic
мала точность Т1спытаний; композиционных материалов, вследствие малой разрешаемой. способности метода, в котором пространство между исделием и детектором заполнено газом.T1 trial accuracy is low; composite materials, due to the low resolvability. ability of the method in which the space between the product and the detector is filled with gas.
Дл повыщени точности при исшлтании композиционных материалов между исследуемым изделием и детектором создают ва- куум , а о моменте по влени трещин суд 7 по импульсным сигналам на выходе детек .тора электронов,In order to increase the accuracy of composite materials between the test product and the detector, a vacuum is created, and the moment of occurrence of cracks in the court 7 on the pulse signals at the output of the electron detector,
Испыть Бают изделие следующим образом В процессе механического нагружени здели в месте возможного возникновени трещин размещают детектор апектронов, между изделием и детектором создают вл-i куум, причем при испытании изделий больщих размеров дсх;таточн6 создать вакуум лишь между небольш} м участком поверхности ко- дели и детектора, регистрируютэмиссию электронов с поверхнсх;ти издел1 Я, а о мо менте по влени трешин суд т по импульсным сигналам на выходе детектора, после по влени эмиссии нагружение прекращают ;Я фиксируют величину нагрузки.Test The product is as follows. During the mechanical loading, a detector of apectrons is placed in the place of possible occurrence of cracks, a vacuum is created between the product and the detector, and when testing products of large dimensions dcx, a vacuum is created only between a small part of the surface of the engine. and the detector, register the emission of electrons from the surface; these are parts of I, and the moment of the occurrence of cracks is judged by pulsed signals at the detector output; after the occurrence of emission, the loading is stopped; load.
