A frequency-based modeling approach has been developed for the vehicle fitted with Hydraulically Interconnected Suspension (HIS) system. This frequency-based model has fewer degrees of freedom (DOF) than the reference time-based model. Several physical parameters of HIS system are selected to analytically investigate their effects on several indicators of vehicle roll, pitch and bounce modes, such as roll and pitch angular acceleration, vertical acceleration, and tire ground force. The HIS system parameters are also coordinately tuned and optimized to meet the ride comfort requirement. The full vehicle drop test is conducted for the experimental validation. The analytical results of the proposed model have a good agreement with the measurements. INDEX TERMS Vehicle suspension, ride comfort, hydraulically interconnected suspension, frequencybased modelling, parameter tuning, experimental validation.

“…39 In this study, the handling requirement of APR-IHPS is also considered to design the capacity of accumulator. Based on equation (36), the static nonlinear stiffness curves of PR-IHPS system can be obtained as shown in Figure 9. It indicates that the stiffness of PR-IHPS system increases with the decrease of accumulator's capacity C a .…”

Instability caused by emergency braking and steering during ambulance operation would easily lead to a sharp rise of blood pressure in patient's head, which would further cause a secondary injury to the patient. Furthermore, the vibration generated by uneven road would result in patient's nausea and deterioration of patient's condition. This article proposes a pitch-roll-interconnected hydro-pneumatic suspension system which can achieve the resistance control for pitch, roll, and bounce modes of ambulances to improve the stability and attenuate the vibration for the lying patients. The ambulance with pitch-roll-interconnected hydro-pneumatic suspension is characterized by 7 degrees of freedom dynamic model, in which the characteristics of pitch-roll-interconnected hydro-pneumatic suspension are explicitly formulized using hydrodynamic equation derivation. A motion-mode energy spectral density method is proposed to decouple the vibration energy for bounce, pitch, and roll modes in frequency domain. Subsequently, the parameter design approach incorporated with the suspension characteristic equations and motion-mode energy spectral density method is also presented to optimize the lying patient's ride comfort and ambulance's handling stability. The numerical simulation results show that the proposed pitch-roll-interconnected hydro-pneumatic suspension system can simultaneously provide pitch-roll-stiffness and damping without generating additional bounce-stiffness, resulting in superior ride comfort and handling stability compared to the conventional suspension.

“…The suspensions are assumed to have the linear spring stiffness ( / ) and damping coefficient ( / ), and the vertical stiffness ( / ) of the tyre is considered to be linear. In order to obtain the linear physical parameters for a two-axle vehicle, a new physical parameter identification method was proposed by Zheng et al, [28]. Based on the assumption of the linearity, they introduced the state variable method (SVM) to identify the modal parameter of the vehicle.…”

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