Abstract
The rollcage for WRC race body/rollcage has been developed and optimized by DFSS methodology. It is designed on the principle of reducing it to a Min. of weight compared to the other OEM and the initial set-up model with the torsional stiffness and strength increased. As a result, 12% increased torsional stiffness, maximized strength and 3.7% weight reduction could be achieved. In terms of economics, it is feasible to have a production cost savings of about 11% per car and the effect is further, considering the development period is substantially decreased, 5 to 2 months. Also, in the process of optimizing rollcage structure, applicable items to monocoque body are suggested by investigating the parts and structures that highly affect the body performance.
