Start year: 2005

Summary: Fatal on-road vehicle rollover accidents have been frequently reported both overseas and in Australia. The detailed causes and mechanisms of these accidents are not well understood. This project aims to develop an integrated vehicle model that not only includes all degrees of freedom of the rigid body motion of vehicle components but also the vibration systems that are formed by the chassis, suspension systems, power steering system, powertrain and tires. The modelling method will be validated experimentally using an existing test rig. It will be used to investigate the causes and mechanisms of on-road rollover and explore the solutions preventing rollover happening both passively and actively.
