“…This is emphasized by an experiment with soil compactors, which has a build-in shaking device. The WBV exposure when doing transit on poor maintained sites turns out to be much higher compared to normal duty (Kordestani et al, 2010). Depending on the kind of commercial vehicles different strategies shows potential for reducing WBV exposure.…”

“…The dynamic pressure-sinkage relationship of a smooth rigid wheel-terrain interaction model was also studied from the literature and experimental observations [10]. In addition, the effect of the rough terrain surfaces and various off-road terrains had been researched for wheelssoil contact model of earth-moving machinery [8,11,12]. All the above results indicated that the vibration responses of interactive models are greatly influenced by deformable soil ground.…”

“…The isolation mounts used for the vibratory roller cab are mostly equipped with the traditional rubber mounts with their stiffness and damping constants [3,13,14]. The influence of the design parameters of the cab rubber mounts on the ride dynamics of the soil compactor was investigated via the analytical and experimental methods [12], and their parameters were then optimized to enhance the driver's ride comfort [17]; however, the vertical driver's seat and cab's pitch vibrations are still great under operation conditions. Consequently, the traditional rubber mounts of the cab are difficult to satisfy the driver's ride comfort.…”

This study proposes a dynamic model of the vibratory roller interacting with the off-road deformed terrain to analyze the lowfrequency performance of three different cab's isolation mounts under the different operating conditions. In order to evaluate the ride comfort of the vibratory roller with the different cab's isolation mounts, a three-dimensional nonlinear dynamic model is established. The power spectral density (PSD) and the weighted root mean square (RMS) of acceleration responses of the vertical driver's seat, cab's pitch, and roll vibrations are chosen as objective functions in the low-frequency range. Contrastive analysis of low-frequency vibration characteristics of the vibratory roller with the traditional rubber mounts, the hydraulic mounts, and the pneumatic mounts is carried out. Experimental investigations are also used to verify the accuracy of models. The research results show that the hydraulic mounts have an obvious effect on mitigating the cab vibration and improving the ride comfort in comparison with the traditional rubber mounts and the pneumatic mounts.

“…Both the plastic and elastic stiffness of soil surface (k sp and k se ) are increased while the elastic damping of the soil surface c se is decreased and the soil layers becomes more elastic. The third-order differeantial equation describing the vertical motion of the vibrating drum is given by Ario Kordestansi et al [3] as follows: …”

“…The ride dynamics of typical North-American soil compactors were investigated via analytical and experimental methods. The 12-DOF in-plane ride dynamic model of a single-drum compactor was formulated through integrations of the models of various components such as driver seat, cabin, roller drum and drum isolators, chassis and the tires [3].…”

Abstract. In this study, based on the analysis of nonlinear geometric characteristics of wheel-deformation of soil ground contact and the weighted r.m.s acceleration responses of the vertical driver's seat, pitch and roll angle of the cab are chosen as objective functions, a 3D nonlinear dynamic model of a single drum vibratory roller was developed based on Adam D. and Kopf F's elastic-plastic soil model and Bekker hypothesis of the soft soil ground. Matlab/Simulink software is used to simulate the nonlinear dynamic models and calculate the objective functions according to the ISO 2631: 1997 (E) standard such as the weighted r.m.s acceleration responses of the vertical driver's seat, pitch and roll angle of the cab. An experiment was set up to measure ride comfort for vibratory roller when vehicle compacts and moves under four different operating conditions. The numerical simulation results for ride comfort analysis were compared with the experimental results whicle have verified the validity of models. Ride analysis results are shown that vibratory roller ride comfort is very poor in the most of the operating conditions. The study can provide a basis for the isolation system optimum design of the off-road vehicle.
