Digital model of GM Racing SB2 NASCAR V8

SAE International has published on its website an Automotive Engineering International case study of the creation by US company Richard Childress Racing of the first 3D model of the GM Racing SB2 engine block. RCR used 'Geomagic Studio' software from Raindrop Geomagic and Parametric Technology's 'Pro/ENGINEER' tool to create an accurate digital replica of the cast part, enabling GM and its NASCAR teams to conduct ongoing engineering analysis studies

RCR has long used scanners and 'Geomagic Studio' software to reverse-engineer cylinder head ports for its Winston Cup race engines. It and other Chevrolet teams are now using the model to run CFD tests to optimize cooling, and for FEA simulations to determine where material can be removed in secondary machining without affecting the strength of the block. The model also provides the foundation for creating a complete digital engine assembly.

RCR is also working on a digital model of a total racecar assembly, complete with surface models of the chassis and the entire powertrain.
