| Abstract: | The desire of car manufacturers is to employ different less dense quality materials to meet the design objectives such as high strength, light weight and high rigidity. It is the fact that the efficiency and driving dynamics of motor sport vehicle are usually influenced by the weight and stiffness of chassis. Though many monocoque composite chassis have been designed, limited works are reported in open literature. The present work focusses design process of the commercial formula SAE monocoque race car chassis that requires a comprehensive analysis concerning all aspects of the chassis, starting from material selection, ply placement and layup sequence through to structural analysis and evaluate the chassis performance against the design requirements. In this work the weight, torsional stiffness and the torsional stiffness to weight ration are identified as key performance parameters. It is found that the chassis rigidity decreases with the increase of torsional stiffness. The results of the study concluded that the torsional stiffness of more than ~3 times the roll stiffness, easily adds more weight than handling performance. The choice of a carbon composite structure for the chassis over a steel space frame leads to great weight savings without compromising on performance. The superior material properties of the unidirectional woven carbon fiber which was considered along with the flexibility in composite layout and core design utilized to arrive an optimized monocoque composite design using ANSYS and achieve satisfactory torsional rigidity with minimal weight. Despite the disadvantages with a carbon composite chassis, namely high cost and difficulty in manufacturing, the conclusion is that the benefits outweigh the drawbacks |
