Formatted abstract
This thesis is a modelling exercise aimed at providing an understanding of UQ Racing’s Formula SAE race car’s behaviour during longitudinal acceleration for optimising and enhancing the team’s capability of winning the Acceleration Event at the FSAE-A 2004 competition.

The methodology is to construct a Simulink model to simulate the behaviour of the race car using researched material. Testing results from actual acceleration runs will be used to develop a tyre curve and verify the model’s accuracy.

Optimisation results show that for Avon race tyres high engine speed gear changes coupled with a launch engine speed profile ranging from 7050 RPM down to 5950 RPM will result in a time of 4.19 seconds. This is a good result from a tyre with a coefficient of friction lower than the sticky Hoosier race tyres normally used by the team.

Using a predicted tyre curve for the Hoosier race tyre, the ‘optimised’ MoTeC and gear change timing variables produce a 75 m sprint time of 3.97 seconds.
