Živalič, Jakob (author), Kalin, Mitjan (mentor), Požar, Tomaž (comentor)

S poznavanjem vpliva izolacije vzorcev na kontaktno temperaturo pri tribološkem testiranju polimernih materialov lahko bolje načrtujemo izvajanje teh testov in bolje vemo, kaj pričakovati od rezultatov ter kako jih interpretirati. Izvedli smo teste trna na disku (angl. pin on disc), pri čemer smo uporabili trn iz poliacetala (POM), disk iz poliamida (PA66) in izolacijo iz teflona (PTFE). Opravili smo eksperimentalno delo na tribometru v laboratoriju in simulacije na numeričnem modelu na računalniku. Iz rezultatov smo ugotovili, da je vpliv izolacije večji pri pogojih testiranja, ki povečujejo generacijo toplote v kontaktu (večja normalna sila, večja hitrost drsenja) in pri manjših debelinah vzorcev.

• Title: Effect of sample insulation on contact temperature in tribological testing of polymeric materials

Abstract

Knowing how sample insulation impacts contact temperature during tribological testing of polymeric materials facilitates planning the execution of such tests and gives a better insight into the expected results and the interpretation thereof. We conducted pin on disc tests using a polyacetal (POM) pin, a polyamide (PA66) disc, and Teflon (PTFE) insulation. Experimental work was performed on a tribometer in a laboratory and simulations on a numerical model on a computer. The results showed that the effect of insulation is greater under testing conditions that increase heat generation at the contact (higher normal force, higher sliding speed) and with thinner samples.
