Abstract
Big Tyre Pty Ltd has recently patented a non-pneumatic tyre assembly (International Publication No. WO 2006/116807) which it hopes will revolutionise the underground mining industry by eliminating the disadvantages associated with current tyre options. Numerical methods have so far proven insufficient to best approximate the static be-haviour of the wheel; the first prototype/proof of concept having been constructed without positive finite-element analysis (FEA) results.
The prototype behaves as expected at low loads, but is not performing well under the high tonnage loads for which it is designed. Before a second prototype can be constructed, numerical models need to be devised to accurately simulate both static and dynamic behaviours of the already constructed prototype. The FEA model requires non-linear large displacement analysis; current models requiring in excess of 33hours solve time. Thus, there is a requirement for a more streamlined modelling approach.
This project aims to develop a series of numerical models to streamline the engineering, and predict the static performance of BIG TYREs patented non-pneumatic wheel
assembly for varying geometries and material properties.
