Development of a Tyre Model for a Car Simulator<br />
This report is Part B to a previously written project, it contains the method and process of<br />
designing and building a tyre testing rig set up, initially 4 ideas were looked at as potential<br />
projects which later was cut to two, these were then developed in their early stages until it was<br />
decided to go with one, this report explains why. It also goes to explain how data was collected<br />
and transformed into graphical content and used to be part of rFactor tyre data.<br />
Finally the validity of the test rig itself was compared against an industry tyre manufacturer<br />
Avon.<br />
Designing a test rig by recycling old parts and materials, stored at the University of the West<br />
of England was an old ‘Royale Racing’ Formula Ford chassis with most parts still available<br />
including the suspension, wheel, upright, rods and bolts. The idea here was to cut off the front<br />
of the frame where the suspension attaches to, subsequently allowing the wheel to be bolted<br />
to the upright.<br />
The first test was at 500N at 2.5 degrees, then the load<br />
was lowered to 400N still at 2.5<br />
degrees, then 300N and so on. This was repeated till<br />
the 200N test was completed. After<br />
this the tests restarted at 500N for 7 degrees, this<br />
remained the method for testing right<br />
up to 22 degrees of inclination was completed.<br />
A maximum test was conducted at 760N, this load was<br />
placed on the top and bottom<br />
wishbones of the suspension.<br />
Project summary<br />
Development of a Tyre Model for a Car Simulator<br />
This project involved creating a Tyre testing rig and finding<br />
the forces it produces<br />
Project Objectives<br />
It is within the interests of this report to fulfil the<br />
targets what have been set, therefore it was<br />
decided to build a test rig where forces can be<br />
measured per load the tyre is carrying.<br />
This can then be used to form a tyre model for the<br />
simulator rFactor.<br />
Project Conclusion<br />
To conclude the project as a whole, it has been a<br />
successful build where the initial project<br />
aims have somewhat been met, industry standard<br />
graphs for Lateral Force vs Slip Angle have<br />
been created modelling the performance of the tyre<br />
at certain loads
