Formatted abstract
In the context of the Formula SAE competition, it is of pivotal importance that students develop a strong understanding of the dynamics of the system they are designing, in order to maximise their competitive potential during events.

At present, there exists a requirement for the development and usage of a cheap and reasonably accurate test rig capable of recording, and allowing analysis of, the dynamic response of the vehicle to driver (or road-surface) input. It was therefore the purpose of this study to define and develop a testing rig to perform such a task at little to no cost.

The test rig essentially uses a series of custom developed accelerometer units and linear position sensors, connected through a single data acquisition unit and powered by an external power regulator feeding from the battery of the vehicle.

The test rig was devised and developed to allow quantitative confirmation of modelled vehicle dynamics results that have been developed as part of thesis study by students in previous years. The resultant experimental analysis highlighted some deficiency in the modelling software in its ability to completely and accurately model a dynamic vehicle in a variety of increasing speed and decreasing radius cornering manoeuvres.

The test rig presents a reasonably accurate means of categorising the dynamics of the current Formula SAE vehicle and provides a means for testing and further developing the dynamic capability of the vehicle in coming years.
