(54) СПОСОБ ИСПЫТАНИЯ ЦИЛИНДРИЧЕСКИХ ОБРАЗЦОВ НА СЖАТИЕ(54) METHOD FOR TESTING CYLINDRICAL SAMPLES FOR COMPRESSION
II
Изобретение относитс к испытательной технике, а именно к способам испытани образцов, преимущественно из армированных пластиков на сжатие.The invention relates to a testing technique, and specifically to methods for testing samples, preferably made of reinforced plastics in compression.
Известен способ испытани цилиндрических образцов на сжатие, заключающийс в том, что используют накладку, выполненную с цилиндрической выемкой, в которую устанавливают торцом образец и прикладывают к нему усилие до его разрушени 1.The known method of testing cylindrical compression specimens consists in using an overlay made with a cylindrical recess into which the specimen is installed with an end face and a force is applied to it until its destruction 1.
Недостаток способа заключаетс в том, что происходит разрушение торцов образца в результате приложени сжимающего усили , что снижает точность испытаний.The disadvantage of the method is that the ends of the specimen are destroyed as a result of the application of compressive force, which reduces the accuracy of the tests.
Целью изобретени вл етс повыщение точности испытани полого цилиндрического образца.The aim of the invention is to increase the accuracy of testing a hollow cylindrical sample.
Указанна цель достигаетс тем, что торцы образца заливают св зующим, а выемку в накладке заполн ют шариками, на которые устанавливают торец образца после отверждени св зующего.This goal is achieved by the fact that the ends of the sample are poured into a binder, and the notch in the patch is filled with balls, on which the end of the specimen is placed after curing of the binder.
На чертеже показано устройство дл реализации предлагаемого способа.The drawing shows a device for implementing the proposed method.
Устройство содержит накладку 1, выполненную с цилиндрической выемкой 2 и установленную на плиту 3 пресса, щарики 4, размещенные в цилиндрической выемке 2 накладки 1, щарнир 5, посредством которого накладка 1 взаимодействует с плитой 3 пресса.The device contains a lining 1, made with a cylindrical recess 2 and mounted on the plate 3 of the press, balls 4, placed in the cylindrical recess 2 lining 1, hinge 5, by means of which the plate 1 interacts with the plate 3 of the press.
Способ осуществл ют следующим образом. Торцовую зону образца 6 перед испытанием заливают в металлическом кольце св зующим 7 на определенную высоту в зависимости от величины испытательного усили . Выдерживают образец 6 до отвер1д ждени св зующего 7. В качестве св зующего может быть использована эпоксидна смола.The method is carried out as follows. Before testing, the end zone of sample 6 is poured in a metal ring with binder 7 at a certain height depending on the magnitude of the test force. Sample 6 is held until the binder 7 is open. 7. Epoxy resin can be used as a binder.
Цилиндрическую выемку 2 накладки 1 заполн ют щариками 4. Размещают образец 6 между плитами 3 и 8 пресса и устанавливают его торцом на щарики 4 в выемку 2. Прикладывают сжимающее усилие до нужной величины или до разрущени образца. Св зующее 7, прочно соединенное с боковой поверхностью торцовойThe cylindrical recess 2 of the lining 1 is filled with balls 4. Place the sample 6 between the plates 3 and 8 of the press and install it with the end face on the balls 4 into the recess 2. Apply compressive force to the desired value or until the sample is destroyed. Binder 7, firmly connected to the side surface of the end
20 зоны образца, снимает с торца основную часть усили осевого сжати , равномерно распредел его по боковой поверхности образца .20 of the sample zone, removes from the end the main part of the axial compression force, evenly distributing it along the lateral surface of the sample.
