Computer simulations accelerate the continuous development of the ID. R
The continuous development of the #idr is in full swing. The prototype, powered by two electric motors with a 500 kW (680 PS) system performance, will in summer 2019 hunt down the lap record for electric vehicles on the Nürburgring-Nordschleife with Romain Dumas at the wheel. As well as extensive test drives and the work in the wind tunnel, #Volkswagen Motorsport is also strongly relying on computer simulations in the preparation phase. These digital tools not only represent essential support for the engineers, they also save time and costs.
“While Romain Dumas practices the track or tests various chassis set-ups on the driving simulator, simulation technology also plays a crucial role for the engineers as well,” explains Dr Benjamin Ahrenholz, head of calculation/simulation at #Volkswagen Motorsport. “With regard to the Nürburgring-Nordschleife, we are in the fortunate position of being in possession of a wealth of data on the track layout and road surface. This allows us to adapt the #idr virtually as efficiently as possible, despite the fact it has never driven a lap of the Nordschleife before.”
Whatever Romain Dumas inputs through the virtual cockpit – technically known as “Driver in the Loop” – the computer then builds upon in the offline driving dynamics simulation, whereby it completes, theoretically, an infinite number of laps with a saved profile. In this way, the simulations can determine how different power outputs of the motors or shifts in the vehicle’s centre of gravity affect the ultimate lap time. This is all with the aim of optimising the handling of the car and the responsiveness of the motors.
In the flow simulation, the #Volkswagen Motorsport aerodynamics department uses CFD (Computational Fluid Dynamics) technology to study how the airflow is channelled around the #idr as well as through the cooling systems most effectively. The ideal compromise between downforce and aerodynamic drag is sought after. Battery simulation compares power management and recuperation strategies to ensure the most efficient use of the electrical energy, which is stored in the batteries and recovered during braking.
Finally, the structure simulation deals with the mechanical design of individual components. The Nürburgring-Nordschleife poses high demands on the structure of the race car. A focus of the structure simulation is therefore to calculate the loads on the chassis, suspension and bodywork of the #idr. For example, the so-called topology optimisation is something also employed in the development of production vehicles. A typical task is to design a component within a given space. Whereas in production vehicle development the requirements mostly relate to durability and economical construction, the priorities concerning the #idr are both ensuring necessary stability while also keeping the car as light as possible.
