Description
Предметом изобретени вл етс способ определени сопротивлени усталости материалов при одноосном напр женном состо -нии, а также устройство, служащее дл осуществлени предложенного способа.The subject of the invention is a method for determining the fatigue resistance of materials under a uniaxially stressed state, as well as a device for implementing the proposed method.
Отличительна особенность этого способа заключаетс в том, что образец материала попеременно подвергают нагреванию и охлаждению и определ ют число этих циклов до его разрушени .A distinctive feature of this method is that the sample of material is alternately subjected to heating and cooling and the number of these cycles is determined before its destruction.
Этим обеспечиваетс возможность определени термической стойкости в зависимости от заданных напр жений.This makes it possible to determine the thermal resistance depending on the set voltages.
Устройство дл осуществлени описываемого способа содержит нагревательную печь с автоматическим управлением, неподвижный и подвижный захваты и рычажное нагрузочное приспособление.A device for carrying out the described method comprises a heating furnace with automatic control, fixed and movable grippers and a lever loading device.
Отличительна особенность устройства заключаетс в том, что его рычажное нагрузочное приспособление выполнено в виде сдвоенных рычагов первого и второго рода. Рычаги взаимодействуют с двойной серьгой , жестко св занной с подвижным захватом. Этим обеспечиваетс приложение к образцу переменно сжимающих и раст гивающих усилий.A distinctive feature of the device is that its lever loading device is made in the form of twin arms of the first and second kind. The levers interact with a double earring rigidly connected to a moving gripper. This provides an application to the sample of alternating compressive and tensile forces.
На чертеже изображена принципиальна схема предлагаемого устройства .The drawing shows a schematic diagram of the proposed device.
Дл установки образца / испытываемого материала в устройстве применены нижний и верхний захваты 2 и 5.The lower and upper grippers 2 and 5 are used to install the sample / test material in the device.
Верхний захват 3 выполнен подвижным и соединен с двойной серьгой 4. Последн служит дл соединени рычагов 5 первого и второго рода, высоту подъема концов которых определ ют по индикаторам 6. Рычаги 5 могут поворачиватьс относительно опор 7. На концах этих рычагов подвешены тарелки с грузами 8. Винты 9 предназначены дл поддержани рычагов 5 в горизонтальном положении. Дл обеспечени возможности регулировани положени нижнего захвата 2, последнийThe upper grip 3 is made movable and connected to a double earring 4. The latter serves to connect the levers 5 of the first and second kind, the height of the ends of which are determined by the indicators 6. The levers 5 can rotate relative to the supports 7. The plates with weights are suspended at the ends of these levers 8 The screws 9 are designed to maintain the levers 5 in a horizontal position. To enable the position of the lower grip 2 to be adjusted, the last
выполнен с возможностью передвижени вдоль его оси. Нагрев и охлаждение образца / осуществл етс посредством нагревательной печи 10 с автоматическим управлением.made with the possibility of movement along its axis. The heating and cooling of the sample / is carried out by means of a heating furnace 10 with automatic control.
