In 2009, Taylormade Racing, a small Californian composite firm, decided to build a Grand prix bike to showcase its carbon-fibre expertise. British-based designer John Keogh, in partnership with Paul Taylor, decided that the recently introduced moto2 class-with a stock Honda CBR 600 engine but completely free chassis rules – would allow full vent to their ideas without having to worry about engine development. Keogh immediately set to work drawing up the general layout and ignoring pretty much all the normal conventions of motorcycle design: The new design would have a radiator under the seat (rather than in front of the engine) and a wishbone suspension system (instead of telescopic forks). In addition, it would have a full monocoque chassis with carbon-fibre as its material, and a swing-arm of the same composite. A tall central fuel tank would be added to minimize weight shift with diminishing fuel load. This clashed with the need to duct air from the high-pressure on the nose back through the headstock, over the mandated airbox and to the under seat mounted radiator. The solution: a ‘doughnut’ duct that would go straight through the middle of the fuel cell. CASE STUDY l REVERSE ENGINEERING AN UNIQUE MOTORBIKE BODY DESIGN USING REXCAN CS PLUS SOLUTION & RESULT 3D scan Alliance, a UK consultancy, suggested the best 3D scanning equipment and process for the team’s requirements. It recommended a ‘structured light’ 3D scanner. Structured light scanners are often more associated with metrology type applications due to their potentially ultra-high accuracy and resolution. The suggested Solutionix Rexcan CS was selected for its fast ‘Blue LED’ technology. Capable of scanning the dark surface of the body panels in 1.5 hours in total, the subsequent mesh processing took about 30 minutes. The full digital representation of the bodywork, that was taking shape in the US, could now be shared between design work in the UK and other contributing parties. “The scanning process was absolutely vital to us, not only in giving correct body data for modeling but in solving the heating problem via CFD. Furthermore, not only is the Solutionix a quick and highly accurate process it is allowing us to correlate any modifications and refine the performance of the bike further. It is an invaluable part of the design process.” The end result is a highly potent race bike with a unique design heavily reliant on reverse engineering through scanning and hands-on modeling.
