International Journal of Vehicle Design (IJVD), Vol. 44, No. 3/4, 2007

Abstract: In this paper, the design procedure for a new chassis concept for competition go-karts is presented. Such a vehicle requires an unconventional design procedure for the frame due to the lack of suspensions and the need to sustain load transfer from the ground with the help of the tyres' radial stiffness. A sandwich panel built with a lightweight aluminium honeycomb core and carbon skins is proposed. An optimal sandwich stacking has been found imposing the same torsional stiffness and the same margin of strength typical of a traditional metal space frame. The effects on global vehicle performances have been evaluated by means of a simulation programme based on compliance data calculated by means of finite elements analysis.
