Određivanje koeficijenta trenja pređa primenom metode adaptirane strme ravni

Abstract

Razvijena je metoda za određivanje koeficijenta trenja pređa adaptacijom uređaja za određivanje koeficijenta trenja tekstilnih površina zasnovanog na principu strme ravni. Metoda je bazirana na primeni Amontonovog zakona i omogućava određivanje koeficijenta trenja pređe o metalnu površinu. Rezultati koeficijenta trenja prede o metalnu površinu dobijeni primenom metode adaptiranog dinamometra, koju su autori rada ranije razvili, potvrdili su uspešnost metode prikazane u ovom radu.

In this paper, method for determination of yarn friction coefficient on the apparatus, which is already used for determination of textile surfaces friction coefficient, was developed. The way on which adapted apparatus functions is based on the application of Amonton's law, i.e. on the principle of the inclined plane. This method made it possible the friction coefficient of the yarn/metal surface interface to be determined. Results of the yarn/metal surface interface friction coefficient, obtained by the application of the method of adapted dynamo meter, which has been earlier developed by the authors, confirmed the successfulness of the presented method.
