Development of vibration isolation models in vibratory roller’s seat and cabin: A survey

Under the impaction of excitation forces of the elastic tire/rigid drum and off-road soil ground interactions, the vibratory roller’s ride quality had been strongly influenced. Thus, the vibration isolation models and structures of the vehicle’s cabin and seat are studied and improved for enhancing the vehicle’s ride quality. To have an overview of the study and development process of the seat suspensions and cabin isolations, this research provides the overall view of the seat and cabin’s vibration isolation models developed and applied to the vibratory rollers based on the results of the existing studies. The study shows that with the semiactive hydraulic isolations (HIs) or semiactive pneumatic-hydraulic isolations (PHIs) applied to the cabin’s vibration isolations, the cabin shaking and driver’s ride quality have been remarkably ameliorated, while, with quasi-zero stiffness elements (QSE) added into the seat suspension, the driver’s ride quality has been greatly ameliorated. Based on the studied results, to control the cabin shaking and enhance the driver’s ride quality, a combination between the cabin’s semiactive HIs and the seat’s QSE should be developed in further studies. © The Author(s) 2023.
