Abstract
1. Способ испытания образца при сжатии на длительную и кратковременную нагрузку, при котором один образец устанавливают между нижней и промежуточной траверсами с опорным шаром, имеющим возможность перемещения, другой - между промежуточной и верхней траверсами, при этом траверсы закрепляют на штангах при помощи гаек, затем производят нагружение образцов посредством герметичной камеры, расположенной под поршнем в цилиндрической полости нижней траверсы и сообщенной с источником давления, отличающийся тем, что перед началом испытаний на штангах между верхней траверсой и гайками устанавливают упорные подшипники, а нагружение образцов производят посредством герметичной камеры в виде металлического сильфона.2. Способ по п.1, отличающийся тем, чтопри проведении испытания одного образца между нижней и промежуточной траверсами устанавливают образец, а между промежуточной и верхней траверсами - макет из материала с повышенной предельной прочностью на сжатие, чем испытуемый образец.3. Способ по пп.1 и 2, отличающийся тем, чтомежду промежуточной и верхней траверсами устанавливают образец, а между нижней и промежуточной траверсами - макет из материала с повышенной предельной прочностью на сжатие, чем испытуемый образец.4. Способ по пп.1-3, отличающийся тем, чтоштанги по всей длине снабжают упорной резьбой, а образец устанавливают между нижней и верхней траверсами, опуская верхнюю траверсу до уровня образца.1. A method of testing a sample under compression for a long and short-term load, in which one sample is installed between the lower and intermediate traverses with a support ball that can be moved, the other between the intermediate and upper traverses, while the traverses are fixed on the rods with nuts, then loading samples by means of a sealed chamber located under the piston in the cylindrical cavity of the lower beam and connected to a pressure source, characterized in that before starting the test on angah between the upper beam and nuts mounted thrust bearings, and loading of the samples produced by the sealed chamber in the form of metal silfona.2. The method according to claim 1, characterized in that when testing a single specimen, a specimen is installed between the lower and intermediate traverses, and a prototype of a material with an increased ultimate compressive strength than the test specimen is installed between the intermediate and upper traverses. A method according to claims 1 and 2, characterized in that a specimen is installed between the intermediate and upper traverses, and a prototype of a material with an increased ultimate compressive strength than the test specimen is installed between the lower and intermediate traverses. The method according to claims 1 to 3, characterized in that the rods along the entire length are provided with a persistent thread, and the sample is installed between the lower and upper traverses, lowering the upper traverse to the level of the sample.
