Quali fasi segue lo sviluppo di un prototipo di auto da corsa endurance per WEC? Come può essere impiegato uno strumento per assistere sia la fase di embodiment design del prodotto che la ricerca delle prestazioni in pista una volta che è stato realizzato?
How is the development of a WEC endurance racing car prototype carried on? How can a tool be employed to assist both embodiment design of the product and performance research on track once it has been produced? In this work will be presented a sort of personal vision of an “how-to guide” to achieve these result (writer is a strongly unexperienced engineer, so take it in mind before fully trust what will be inside this work). Description of the process starts from the conceptual design phase of a racing prototype, to clarify what the experience of senior engineers taught should be taken into account in the specification definition of such a type of race car, moving toward embodiment design phase (when components are designed and produced, and so characteristic performance parameters frozen) until the natural conclusion for each race car project: racing on track. Performance department of the design team exploited some different tools to assist and drive development phases, aiming at targets set in conceptual phase and also at some found out to be relevant during racing season (physiological process since we are speaking of a rookie team in the category the prototype would have raced in). Among the useful aforementioned tools, a full vehicle model is somehow essential, and that is the main subject of this work. Process of integration with design process and trackside activities will be described, showing how useful can be having a powerful computational tool disclosing to designers the implications of the batch of possible engineering choices that has to be done along the way to the racetrack. Full vehicle model was developed inside Canopy Simulations® portal, a laptime simulator structured more as a big optimizer, no driver model, no target trajectories, no target laptimes, but only huge optimization problems targetting the minimum possible resulting laptime; this kind of model substituted previously in-house existent ones, improving a lot performance-related evaluations and making more efficient the decision process of engineering development loops. In final part of this work, it will be showed a brief overview of how in real-case scenarios this kind of tool was employed: definition of suspension kinematic options to be used on different tracks, use of engine specific fuel consumption dyno data to define strategies chosen for different races, FEA analyses validation from real telemetry data, correlation process with telemetry data to improve model reliability… are some of the ways the team exploited the potential of this kind of simulation tool.
