Eksperimentalna vrednotenja za določitev zdržljivosti pnevmatik

Rožman, Jernej (author), Klemenc, Jernej (mentor)

Zaključna naloga obravnava zdržljivost pnevmatike pri cikličnem utrujanju. Na njeno zdržljivost vpliva več dejavnikov. Te dejavnike smo identificirali in jih ovrednotiti z rezultati statičnih in dinamičnih preskusov. V prvem delu je predstavljena konstrukcija radialne pnevmatike, lastnosti posameznih sestavnih delov in mehanizmi, ki vplivajo na zdržljivost. V drugem delu smo merili statične veličine, kotalni upor in ovrednotili ciklično utrujanje pri hitrostnih in vztrajnostnih preskusih. Ugotovili smo vplive obremenitve, tlaka in hitrosti na kotalni upor in posledično na zdržljivost pnevmatike.

• Title: Experimental evaluations to determine tyre durability

Abstract

The thesis deals with a problem of tyre durability at cyclic fatigue. There are several factors that affect the durability of a tyre. These factors have been indentified and evaluated on the basis of dynamic and static tests. First, a design of a radial tyre, the characteristics of its components and mechanisms that affect its durability were presented. Then values at static tests and rolling resistance were measured and cyclic fatigue at high velocity and durability tests was evaluated. It was established how load, pressure and velocity affect the tyre rolling resistance and consequently tyre durability.

• Keywords: pressure, tyres, load, velocity, tyre stiffness, rolling resistance, dynamic durability
