Abstract
Изобретение относитс к области машиностроени , а именно к методам исследовани трибологи ческих свойств эластичных материалов. Целью изобретени вл етс повьшение точности определени коэффициента трени эластичного материала. Способ заключаетс в том, что исследуемый материал помещают в обойму 5 с фильерой на ее торце, продавливают его через фильеру 2 с помощью цуансона 1, а величину коэффициента трени определ ют с учетом трени материала по торцу -пуансона и с учетом переменной площади его контакта при продавлива- нии через фильеру. 1 ил. (Л СThe invention relates to the field of mechanical engineering, namely to methods for studying the tribological properties of elastic materials. The aim of the invention is to improve the accuracy of determining the coefficient of friction of an elastic material. The method consists in placing the material under investigation into the holder 5 with the spinneret at its end, pushing it through the spinneret 2 with the help of a tuson 1, and the value of the coefficient of friction is determined taking into account the friction of the material along the end of the punch and pushing through a die. 1 il.

На чертеже схематически изображено устройство дл осуществлени предлагаемого способа.The drawing shows schematically an apparatus for carrying out the proposed method.
Устройство содержит пуансон I, фильеру 2 с кольцевым выступом 3, трубу /4 и обойму 5.The device comprises a punch I, a die plate 2 with an annular protrusion 3, a pipe / 4 and a holder 5.
Способ осуществл етс следующим образом.The method is carried out as follows.
Образец 6 из, эластичного материала помещают в обойму 5 и с помощью пуансона 1 под воздействием усили P(S) продавливают материал через фильеру 2, имеющую кольцевой выступ 3. В ходе испытани регистрируют усилие P(S).Sample 6 of elastic material is placed in the holder 5 and using the punch 1 under the influence of force P (S), the material is forced through the die plate 2 having an annular protrusion 3. The force P (S) is recorded during the test.
По результатам испытани определ ют коэффициент трени , который расчитывают по формулеThe results of the test determine the coefficient of friction, which is calculated by the formula
