Note: With the Singapore leg of the FIA (Fédération Internationale de l'Automobile) Formula One World Championship coming up this weekend, MIS-Asia.com will be looking at the impact of technology on Formula One (F1) racing. In the second of an ongoing series, Jack Loo speaks to blogger John Flood, who owns and edits the site formula1journal.com , which covers some of the key technologies used in the F1 competition today.
There is much talk about Computational Fluid Dynamics (CFD) this season. How is this technology used in F1 today?
The use of CFD allows designers to test the overall effect of a cars shape without building a car. Multiple designs could be mooted and tested in CFD without the expense and time of manufacturing failed concepts. The computing power necessary to crunch the massive numbers requires supercomputer hardware and software capable of exploiting the hardware’s capacity.
The CFD and CAD (Computer-Aided Design) data could now be used to manufacture scale models of the car to be used in rolling wind tunnel testing. The data needed to be integrated between the CAD files, the CAM (Computer-Aided Manufacturing) files, and the wind tunnel data. Product Lifecycle Management (PLM) is the solution. The data collected in the tunnel needed to be calibrated vis-à-vis the CFD data: in other words, actual data versus conceptual data. Plus, corrections between scale model data and full scale data needed to be applied.
