Description
Изобретение относитс к области акустических измерений и может быть использовано дл определени собственных частот и логарифмического декремента затухани колебаний образцов и изделий из полимерных материалов дл неразрушающего контрол качества резонансным методом.The invention relates to the field of acoustic measurements and can be used to determine the natural frequencies and the logarithmic decrement of oscillation damping of samples and products made of polymeric materials for non-destructive quality control using the resonant method.
Известны стенды дл определени параметров вибраций образцов материалов, содержащие основание с нанравл ющими, опоры дл креплени образца и экранирующие корнуса с размещенными в них электромеханическими преобразовател ми дл возбуждени и приема колебаний.There are known stands for determining the vibration parameters of samples of materials, which contain a base with nanofillers, supports for fastening the sample and shielding the corns with electromechanical transducers placed in them for exciting and receiving vibrations.
Предложенный стенд отличаетс от известных тем, что, с целью повышени точности измерени корпуса установлены непосредственно на направл ющих, а опоры размещены на корнусах. Дл того, чтобы испытывать образцы разных форм и габаритов оноры прикрепл ют к корпусам посредством магнитной св зи . Кроме того, с целью плавного перемещени преобразователей, а также испытани образцов при разных видах колебаний, стенд снабжен щарикоподшипниковыми механизмами , кинематически св зывающими корпуса преобразователей с одной из направл ющих.The proposed stand differs from those known in that, in order to improve the accuracy of measuring the body, they are mounted directly on the guides, and the supports are placed on the corns. In order to test samples of various shapes and sizes, hears are attached to the housings by magnetic coupling. In addition, in order to smoothly move transducers, as well as test samples with different types of vibrations, the stand is equipped with ball bearing mechanisms that kinematically connect transducer housings with one of the guides.
Стенд содержит экранирующие корпуса / и 2, выполненные в виде массивных плит из магнитного материала. В корпусах установлены электромеханические преобразователи 3, 4 дл возбулсдени и приема колебаний. Кроме того, стенд и.меет направл ющие 5 цилиндрической формы дл установки корпусов и шарикоподшипниковые механизмы 6 дл их илавного иеремещени , опоры 7 дл креилеПИЯ иснытуемого образца 8 и основание 9.The stand contains a shielding housing / and 2, made in the form of massive plates of magnetic material. Electromechanical transducers 3, 4 are installed in housings for exciting and receiving oscillations. In addition, the stand also has cylindrical guides 5 for mounting the housings and ball-bearing mechanisms 6 for their movement and support, 7 for the Creation of the test sample 8 and the base 9.
Электромеханические преобразователи 3, 4 установлены в полост х корпусов при помощи резиновых амортизаторов.Electromechanical transducers 3, 4 are installed in the housing cavity with rubber shock absorbers.
Опора 7 дл креплени образца состоит изThe support 7 for fastening the sample consists of
основани , выполненного в виде магнитного диска и прикрепленного к нему унругого элемента в виде резиновой иолоски, и может быть установлена в любом месте на поверхности корпуса электромеханического преобразовател .the base is made in the form of a magnetic disk and the elastic element attached to it in the form of a rubber and a fiber, and can be installed anywhere on the surface of the housing of the electromechanical transducer.
В корпусах выполиены три взаимно перпендикул рных отверсти , оси которых нересекаютс в одной точке-дл одной нз направл ющих 5 и шарикоподшипниковых механизмов 6, а также два отверсти в перпендикул рных направлени х - дл другой направл ющей 5.In the housings, there are three mutually perpendicular holes, the axes of which do not intersect at one point — for one direction of guide 5 and ball bearing mechanisms 6, and also two holes in the perpendicular direction — for the other guide 5.
