“…The most effective way to reduce the roll vibration without affecting other vehicle performance is to optimize suspension damping. 7,15,16 When the vehicle travels on the uneven road, the axle not only produces vertical motion, but also rotates around the instantaneous center. The vertical vibration of the body is mainly attenuated by the damping force of the shock absorber, and the roll vibration of the body is mainly attenuated by the damping torque.…”

The human body is extremely sensitive to roll vibration, which is also an important indicator for evaluating vehicle comfort. In order to improve the ability of anti-roll vibration of vehicles, the methods of mathematical modeling, dynamic simulation, and vibration test are used in this paper. The generation mechanism, dynamic change law, and key influencing factors of the roll vibration are analyzed. The analysis results include: the dynamic simulation results are in good agreement with the test results, and the use of the simulation model is beneficial to the analysis and control of the roll vibration; the roll vibration is caused by the relative dynamic deformation of the left and right suspensions, and the larger the relative deformation, the more obvious the roll vibration; the optimization of the position and damping of the shock absorber is conducive to the control of roll vibration, which greatly improves the comfort of the vehicle. The research results provide theoretical basis and reference for grasping the characteristics of the roll vibration and vibration reduction design.
