Lap Time Simulation: Comparison of Steady State, Quasi- Static and Transient Racing Car Cornering Strategies 2000-01-3563

Considerable effort has gone into modelling the performance of the racing car by engineers in professional motorsport teams. The teams are using progressively more sophisticated quasi-static simulations to model vehicle performance. This allows optimisation of vehicle performance to be achieved in a more cost and time effective manner with a more efficient use of physical testing.Racing cars are driven at the limit of adhesion in the non-linear area of the vehicle's handling performance. Previous simulations have modelled the transient behaviour by approximating it with a quasi-static model which ignores dynamic effects, for example yaw damping. This paper describes a comparison between different cornering modelling strategies, including steady state, quasi-static and transient. The simulation results from the three strategies are compared and evaluated for their ability to model actual racing car behaviour.
