Design and Optimization of a Space Frame Chassis

摘要

This work is a contribution to the development of a 3-D space frame vehicle structure design and numerical optimization applied to a high-performance roadster vehicle. For this type of vehicle, a chassis must be as rigid and lightweight as possible in order to fulfill driveability (the degree of smoothness and steadiness of acceleration of an automotive vehicle) and maneuverability (the quality of being capable of maneuvering or changing position) requirements. Some difficulties in obtaining the optimum design by using analytical formulation are encountered, because this real structure is a complex geometry one.
