Description
Изобретение относитс к области испытательных машин, в которых используетс неразрушащий метод контрол качества материалов .This invention relates to the field of testing machines that use a non-destructive method to control the quality of materials.
Известны устройства дл контрол прочностных характеристик сварных соединений, содержаище излучатель, установленный вблизи сварного шва, и приемники акустических колебаний.Devices are known for monitoring the strength characteristics of welded joints, containing an emitter mounted near the weld, and receivers of acoustic oscillations.
Цель- изобретени - повышение точности контрол .The purpose of the invention is to improve the accuracy of control.
Это достигаетс тем, что в предложенном устройстве два приемника включены дифференциально и расположены симметрично по отношению к излучателю на рассто НИИ, равном ширине контролируемой зоны сварного соединени .This is achieved by the fact that in the proposed device two receivers are switched on differentially and are located symmetrically with respect to the radiator at a distance of a scientific research institute equal to the width of the controlled zone of the welded joint.
На чертеже изображена схема предложенного устройства.The drawing shows a diagram of the proposed device.
Устройство содержит излучатель I, в качестве которого используетс , например, магнитострик ционный вибратор,два приемника 2,3The device contains an emitter I, which uses, for example, a magnetostrictive vibrator, two receivers 2,3
включенные дифференциально и расположенные симметрично по отношению к излучателю 1 на рассто нии, равном ширине контролируемой зоны 5 сварного соединени , differentially connected and located symmetrically with respect to radiator 1 at a distance equal to the width of the controlled zone 5 of the welded joint,
Приемники 2,3 и излучатель I устанавливаютс на общем резиновом, основании 4, установленном с помощью присосов 5 на контролируе0 мом объекте 6,Receivers 2,3 and emitter I are mounted on a common rubber base 4 installed with the help of suckers 5 on a controlled object 6,
i Излучатель I возбуждает акустические колебани в контролируемом объекте 6, а приемники 2,3 измер ют логарифмический декре5мент затухани колебаний, распростран ющихс от точки возбуждени по основному сечению объекта 6 и поперек сварного шва 7, По выходному сигналу включенных дифферёнциально приемников 2,3 суд т о прочностных характеристиках контролируемого участка,i The emitter I excites acoustic oscillations in the controlled object 6, and the receivers 2,3 measure the logarithmic decrement of the attenuation of oscillations extending from the excitation point over the main section of the object 6 and across the weld 7, On the output signal of the switched differential receivers 2.3 about the strength characteristics of the controlled area,
