Abstract
1. Способ определения долговечности конструкционных материалов в условиях воздействия факторов, заключающийся в том, что круглый плоский образец закрепляют по кольцевому контуру в соединительно-герметизирующем устройстве, термостатируют образец в термостатической камере, разделенной соединительно-герметизирующим устройством с закрепленным в нем образцом на нагнетательную и рабочую камеры, со стороны нагнетательной камеры нагружают образец давлением жидкой или газообразной среды, инертной по отношению к материалу испытуемого образца; со стороны рабочей камеры образец подвергается воздействию любых агрессивных сред и/или агрессивным воздействиям; измеряют время до разрушения образца при задаваемых условиях (температура и механическое напряжение в образце, деформированном давлением среды в нагнетательной камере), на основе полученных данных рассчитывается долговечность материала для заданного набора агрессивных воздействий. ! 2. Устройство для осуществления способа по п.1, содержащее термостатируемую камеру, разделенную соединительно-герметизирующим устройством с закрепленным в нем по кольцевому контуру образцом на нагнетательную и рабочую камеры, источники давления инертной и агрессивной сред, датчик давления инертной среды, датчик расхода инертной среды, термостатирующее устройство с датчиком температуры, блок ввода, вывода и анализа агрессивной среды, источник агрессивной среды, источники других агрессивных воздействий (напр., проникающих излучений), датчики интенсивности других агрессивных воздействий, блок управления источниками других агрессивных воздействий, блок регистрации, анал�1. A method for determining the durability of structural materials under the influence of factors, namely, that a round flat sample is fixed along an annular contour in a connecting and sealing device, the sample is thermostated in a thermostatic chamber, separated by a connecting and sealing device with a fixed sample in it for discharge and working chambers, from the side of the injection chamber, load the sample with the pressure of a liquid or gaseous medium inert to the material of the test sample ca; from the side of the working chamber, the sample is exposed to any aggressive environments and / or aggressive influences; measure the time to failure of the sample under specified conditions (temperature and mechanical stress in the sample, deformed by the pressure of the medium in the injection chamber), based on the data obtained, the durability of the material is calculated for a given set of aggressive influences. ! 2. The device for implementing the method according to claim 1, containing a thermostatic chamber, separated by a connecting-sealing device with a sample fixed in it along the annular circuit into the injection and working chambers, inert and aggressive medium pressure sources, inert medium pressure sensor, inert medium flow sensor , thermostatic device with temperature sensor, input, output and analysis unit for aggressive media, source of aggressive media, sources of other aggressive influences (e.g. penetrating radiation), dates intensity of other aggressive influences, control unit for sources of other aggressive influences, recording unit, anal�
