Изобретение относитс к испытательной технике и может быть использовано при испытани х образцов тонкостенных труб.The invention relates to a testing technique and can be used in testing samples of thin-walled pipes.
Известен способ испытани тонкостенных трубчатых образцов при высоких (низких) температурах, заключающийс в нагреве (охлаждении) образца в печи (криостате) и его деформировании.A known method for testing thin-walled tubular samples at high (low) temperatures, consists in heating (cooling) the sample in a furnace (cryostat) and deforming it.
Предлагаемый способ отличаетс от известного тем, что полость образца на длине, превышающей длину рабочей части, заполн ют теплопроводным материалом, например медной дробью, свободно перемещающимс при изменении температуры и деформировании образца.The proposed method differs from the known one in that the sample cavity at a length exceeding the length of the working part is filled with heat-conducting material, for example, copper shot, which can freely move when the temperature changes and the sample is deformed.
Это позвол ет получить равномерное распределение температуры по поверхности образца .This allows uniform temperature distribution over the sample surface.
Образец тонкостенной трубки наполн ют теплопроводным материалом, например медной дробью, свободно перемещающимс в нем, нагревают в печи и затем деформируют.A sample of a thin-walled tube is filled with heat-conducting material, such as copper shot, freely moving in it, heated in an oven and then deformed.
Тепловые потоки от одних участков рабочей части образца к другим передаютс не только по тонкой стенке образца, обладающей большим тепловым сопротивлением, но и через теплопроводный материал, например медную дробь, что способствует достижению равномерного распределени температуры.Heat flows from some areas of the working part of the sample to other parts are transmitted not only along the thin wall of the sample, which has a high thermal resistance, but also through a heat-conducting material, such as copper shot, which helps to achieve uniform temperature distribution.
