Abstract: The Suzuki optimisation system has been developed to investigate a lightweight vehicle subject to constraints on displacement and eigenfrequency in a simple model. The application of the system to several vehicles with different structures in their early design stage demonstrated that a reduction in structural weight was achievable under most design constraints. As a result, the future applicability of the system over the optimisation of vehicle body structure was confirmed to a certain extent.
