Description

Конструкции ультразвуковых приборов и приспособлений, предназначенные дл  определени  упругих свойств на образцах горных пород и других материалов, состо щие из генераторов высокочастотных импульсов осциллографа и датчиков (излучател  и приемника ультразвука ), известны. Однако эти приборы и приспособлени  требуют параллельную пришлифовку образцов, позвол ющую получать при одной фиксированной длине только одно значение скорости, которое может быть случайным дл  данного образца.The designs of ultrasonic devices and devices designed to determine the elastic properties of rock samples and other materials, consisting of oscillator high-frequency pulse generators and sensors (radiator and ultrasound receiver), are known. However, these devices and devices require parallel grinding of samples, which allows to obtain, with one fixed length, only one value of speed, which may be random for a given sample.

Предлагаемое приспособление позвол ег сделать любое количество определений дл  установлени  средней арифметической скорости распространени  упругих волн и поглощени  звука в образце, так как оно выполнено в виде вращающегос  столика и двух подвижных бабок с преобразовател ми и установленной на задней шкалы с нониусом.The proposed adaptation allows it to make any number of definitions to establish the arithmetic average velocity of elastic waves and sound absorption in the sample, since it is made in the form of a rotating table and two movable heads with transducers and mounted on the back scale with a vernier.

На чертеже показано приспособление в двух проекци х.The drawing shows the fixture in two projections.

Приспособление состоит из двух бабок: передней / и задней 2, соедипенных подвижно при помощи направл ющих 3 и несущих пьезокристаллические излучатели (датчики). В задней бабке 2 перемещаетс  пи}юль 4, внутри которой закреплен корпус пьезодатчика с пьезокристаллом 5. На поверхности пиноли 4 нанесена щкала с ценой делени  1 ммШкала снабжена нониусом 6, неподвижно укрепленным на корпусе задней бабки 2. Нониус позвол ет производить отсчет с точностью до 0,05 мм. Пиноль перемещаетс  внутри задней бабки 2 при помощи шестеренки 7, соединенной с зубчатой рейкой в нижней части. В переднюю бабку / входит и закрепл етс  винтом 8 шпиндель 9, несущий, так же как и пииоль , корпус пьезодатчика с пьезокристаллом, укрепленным внутри корпуса .The device consists of two attendants: the front / and rear 2, which are movably connected using the guides 3 and carrying the piezocrystalline radiators (sensors). In the tailstock 2, pi} yuli 4 is moved, inside which the body of the piezoelectric transducer with piezocrystal 5 is fixed. On the surface of the quill 4 there is a cheekbone with a dividing price of 1 mm. 0.05 mm. The quill is moved inside the tailstock 2 by means of a gear 7 connected to a rack in the lower part. The spindle 9, which, as well as the piol, holds the piezoelectric body with a piezocrystal mounted inside the body, enters the front headstock / is fastened with a screw 8.

Подводимые к пьезокристаллу электрические импульсы генерируютс  генераторами высокочастотных импульсов. Ультразвуковой импульс , создаваемый одним из кристаллов при помощи звуконесущего .стержн  10, передаетс  на испытуемый образец, с которого снимаетс  другим звуконесущим стержнем Л и передаетс  на принимающий пьезокристалл. Рассто ние между концами звукопесущих стержней отсчитываетс  по шкале бабки 2. Врем  пробега ультразвукового импульса фиксируетс  на экране электронно-лучевой трубки катодного осциллографа . После установлени  нулевого или исходного положени  (концеThe electric pulses applied to the piezocrystal are generated by high-frequency pulse generators. An ultrasonic pulse generated by one of the crystals with the aid of a sound-carrying rod 10 is transmitted to the test sample, from which it is removed by another sound-carrying rod L and transmitted to the receiving piezocrystal. The distance between the ends of the sound-supporting rods is measured on the scale of the headstock 2. The travel time of the ultrasonic pulse is recorded on the screen of the cathode-ray cathode oscilloscope screen. After establishing zero or initial position (end
