A novel kinetic dynamic suspension (KDS) system is presented for the cooperative control of the roll and warp motion modes of\noff-road vehicles. The proposed KDS system consists of two hydraulic cylinders acting on the antiroll bars. Hence, the antiroll bars\nare not completely replaced by the hydraulic system, but both systems are installed. In this paper, the vibration analysis in terms\nof natural frequencies of different motion modes in frequency domain for an off-road vehicle equipped with different configurable\nsuspension systems is studied by using the modal analysis method.Thedynamic responses of the vehicle with different configurable\nsuspension systems are investigated under different road excitations and maneuvers.The results of themodal and dynamic analysis\nprove that the KDS system can reduce the roll and articulation motions of the off-road vehicle without adding extra bounce stiffness\nand deteriorating the ride comfort. Furthermore, the roll stiffness is increased and thewarp stiffness is decreased by the KDS system,\nwhich could significantly enhance handing performance and off-road capability.
