Design and Software Base Modeling of Anti-Roll System 2002-01-2217
This paper focuses on design and modeling of anti-roll system for a subcompact passenger car. The system consists of Hydraulic Assisted torsion bars on car suspensions, a hydraulic power unit, and controls. A 158 degrees of freedom model of the car basic dynamics is made in ADAMS software. A bond graph model of the hydraulic anti roll system is contracted and its state equations are entered into MATLAB/Simulink. The two software are linked and a complete model is made for study and controller design. This paper introduces the method as a useful tool for vehicle dynamics studies and discusses the problems and advantages of the method.
