Project Member(s): Zhang, N., Huang, S.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2007

Summary: This project will develop a theoretical basis for the design of demand dependent active suspensions that prevent vehicle rollovers caused by over steering. The suspensions intend: to feature low cost hybrid absorber-actuators, fluid circuits interconnecting the four wheel stations, and minimal energy requirement; to break the compromise between ride comfort, road holding and vehicle handling, inherent in most existing vehicles. An experimental facility based on a half car configuration and a prototype car will be developed to validate the analytical findings and demonstrate the superior performance in preventing rollovers. The research intends to help reduce road deaths and injuries and save many billions of dollars annually world wide.
