(54) ПРИСПОСОБЛЕНИЕ ДЛЯ ИСПЫТАНИЯ ТРУБЧАТЫХ ОБРАЗЦОВ МАТЕРИАЛОВ НА ПОЛЗУЧЕСТЬ(54) DEVICE FOR TESTING TUBULAR SAMPLES OF CASE MATERIALS

;Изобретение относитс  к области исследо- вани  прочностных характеристик материалов , а именно к приснособлени м дл  иссле довани  трубчатых образцов на ползучесть в канале реактора., Известно приспособление дл  испытани  трубчатых образцов, содержащее корпус, к торцам которого жестко креп тс  голов ки образца, размещаемого внутри корпуса. Цель изобретени  - повышение точности испытани . Дл  этого приспосо.бление снабжено втулкой, размещенной внутри корпуса,а корпус выполнен в виде сильфона, опирающегос  внутренней поверхностью на втулку В процессе нагружени  внешним давлением торцы образца ivioryT смещатьс  из-з податливости корпуса, а в образце обеспечиваетс  напр женное состо ние, близкое к одноосному и определ емое с большей точностью, чем в известном приспособлеНИИ .. fc, Дл  обеспечени  одновременного испытани  образца на различных уровн х напр жений его рабоча  часть выполнена с различной толщиной стенки. На чертеже изображено предлагаемое приспособление. Предлагаемое приспособление содержит корпус 1, к торцам которого жестко креп тс  головки образца 2, размещенного внутри корпуса. Корпус выполнен в виде сильфона, опирающегос  внутренней поверхностью на втулку 3, Последн   дл  удобства сборки разрезана по образующей. Приспособление работает следующим образом. В собранном состо нии его помещают в канал реактора и в процессе облучени  и нагрева подвергают воздействию внешнего давлени , под действие которого в процессе ползучести увеличиваетс , внутренний диаметр образца. Периодические измерени  , диаметра образца дают информацию о ползучести. Предмет изобретени  Приспособление дл  испытани  трубчатых образцов материалов на ползучесть,The invention relates to the field of investigating the strength characteristics of materials, namely to devices for studying creep specimens in a reactor channel. A device for testing tubular specimens is known, comprising a housing, to the ends of which the heads of the specimen placed inside the case. The purpose of the invention is to improve the accuracy of testing. For this purpose, the fitment is provided with a sleeve placed inside the body, and the body is designed as a bellows, supported by the inner surface of the sleeve. uniaxial and determined with greater accuracy than in the known device. fc. To ensure simultaneous testing of a sample at various levels of stresses, its working part is made with different wall thickness. The drawing shows the proposed fixture. The proposed device includes a housing 1, to the ends of which the heads of the sample 2, which is placed inside the housing, are rigidly attached. The body is made in the form of a bellows, supported by the inner surface of the sleeve 3. Last, for convenience of assembly, is cut along a generatrix. The device works as follows. In the assembled state, it is placed in the reactor channel and, during irradiation and heating, is subjected to external pressure, under the action of which the internal diameter of the sample increases during the creep process. Periodic measurements of the sample diameter give creep information. The subject matter of the invention is a device for testing tubular samples of materials for creep,
