In motorsports time is usually limited. With use of dedicated tools for measuring wheel alignment,
camber, ride heights etc. setting up the car can be done fast and consistent. With the setup
sequence and tools described in this report, progress has been made in the time it takes to set up
the car. Also progress was made on the reproducibility of the setups used during the 2013 season.
For this reason it is advised to continue designing these tools for future cars to ease setting up the
Simulating laptimes is a great tool for making design choices. This report describes improvements
made to use the laptime simulations on-track and improvements made to increase the accuracy of
the simulation output w.r.t. test data. These improvements are made by implementing motor data
provided by the motor manufacturer and measurement data from the Apollo slick tyres. The
simulation output of the improved model showed a more realistic comparison with the test data
during the 2013 season, and with the on-track use of the model it provides a great tool for the
With use of the laptime simulation tool the sensitivity analysis has given great insight on the
importance of parameters such as the tyre friction coefficient, vehicle mass, aerodynamic
downforce, and torque distribution. These are just some of the parameters which have substantial
effect on the event laptimes.
Using an optimization algorithm in MATLAB the designs for the URE08/09/10 are optimized for
faster laptimes per event. The outcome of this study shows the "optimal" design for each event
which gives insight on the setup differences between the events. The design of the URE08 has no
aerodynamics and the URE10 has four wheel drive. The outcome of the optimization has shown that
for the different designs "the optimal values" for parameters such as wheelbase and weight distribution differ.
