Finite elemental analysis questions
Question 1
Part A (14marks)
Answer all parts to the question. (a) Physical testing is very expensive in aircraft tyre
manufacturing process, for example tyre foot print and fatigue evaluations. Aircraft tyre
manufacturers are therefore using FE and other CAD/analysis packages to make virtual
simulations of such experiments. As part of a team responsible for such modelling you are
required to develop a FE model for a wheel and tyre contact simulation and consequently to
model the latter rolls on a flat ‘rigid’ surface that simulates the road-tyre interaction. The
constant temperature of the tyre will be assumed to be 20oC. The cross-section of the tyre
is shown in Figure Q1a, and its main parts are labelled. You are required to briefly
summarise what type of analysis is required and what technical data will be needed to
develop a wheel and tyre FE contact model.
