- The ‘roll center’ concept has existed in vehicle dynamics for decades. However, its application is not commonly well understood. This paper considers roll center concepts in the modeling of a planar (front view) twin-beam suspension. Two roll center models are developed and compared to a third model, developed from the Lagrangian method without reference to a roll center.In addition to discussion of the equations of motion, analysis includes simulation of a ‘cornering’ maneuver. The effects of tire vertical stiffness, jacking forces, and nonlinear kinematics are investigated. Conclusions are drawn regarding the usefulness and accuracy of the roll center modeling.
