In an effort to improve the safety and road-holding capabilities of vehicles, manufacturers have begun a trend toward increasing vehicle body roll resistance by introducing stiffer roll-stabilizer bars. In this study vehicle suspension and road surface models are developed to investigate the effects of such stabilizer bars on ride quality. The purpose of the research is to determine the need for further studies in the area of active roll stabilizer systems.
Two dynamic vehicle models are developed: the simplified front-car model and the full-vehicle-body three-degree-of-freedom model. The effects of the stabilizer bars on ride quality are then studied through the use of asymmetric road surface profiles. Discrete, periodic, and random road surface models are used to excite the vehicle models. Emphasis is placed on random road models and predicting the vehicle response using spectral input/output techniques.
