“…The QSE added to the seat suspension was built by two horizontal and symmetrical elastic springs. One end of the elastic spring was fixed to the wall and another end was connected to the seat via the sliding guide block and hard bar with a length of c. 20,21,22,54 QSE's model and structure have been illustrated in Figure 18.…”

“…The above research indicated that the QSE added into the seat's suspension was very effective in enhancing the riding comfort of vehicles. 18,20,22,54,[57][58][59][60][62][63][64][65] Therefore, QSE was also developed for vibratory roller seat to augment driver's riding comfort in the next part.…”

“…However, the research also indicated that the seat's acceleration response in the vertical direction was still high based on ISO 2631-1: 1997. 19 Thus, with the high efficiency of quasi-zero stiffness elements (QSE) embedded into vehicle's seat suspensions for isolating the vibration of the driver, [20][21][22] the QSE's structure was then studied and applied for vibratory rollers' seat suspension for decreasing driver's vibration responses. 7 From the obtained results of isolation systems of the vibratory roller's cabin and seat in existing investigations, this paper reviews a summary of the development of the model and structure of isolation systems of the cabin and seat of vibratory rollers.…”

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.

“…Moreover, a simple structure of the negative-stiffness structures (NSS) was also researched and added into the passive suspension system of the driver’s seat to improve the vehicle’s ride quality. 12–14 The result showed that with the seat suspension added by a simple structure of the NSS, the vehicle’s ride quality was strongly reduced by 75%–80% in comparison without NSS. Especially, the passive seat suspension added by the NSS improved the ride quality better than the semi-active seat suspension while the structure of NSS was much simpler than that of semi-active seat suspension.…”

To evaluate the isolation performance of the negative-stiffness structure (NSS) used by the tuned-mass-damper (NSS-TMD) and the air pistons (NSS-AP) on improving the ride quality of the electrical automobile (EA), an EA’s dynamics model is built under the excitation of the road surface roughness and the in-wheel-motor. Based on the root mean square value of the driver’s seat acceleration response used to assess the driver’s ride quality, two models of the seat suspension added by NSS-AP and NSS-TMD are then simulated to compare the performance between NSS-TMD and NSS-AP in enhancing the ride quality of the EA. The study indicates that both NSS-TMD and NSS-AP added to the seat suspension improve the driver’s ride quality better than the seat suspension without the NSS. Particularly, the root mean square value of the driver’s seat acceleration with the NSS-AP is smaller than that of NSS-TMS by 17.2%. Additionally, when the EA is traveling on the road surfaces of ISO level A, level B, and level C with a high velocity of over 70 km/h, the root mean square value of the driver’s seat acceleration with the NSS-AP is also slowly increased and slower than that of the NSS-TMD. Moreover, the root mean square value of the driver’s seat acceleration with the NSS-AP is also reduced in comparison with the NSS-TMD under the change of the total mass of the in-wheel-motor and the rotor’s eccentricity. Thereby, the NSS-AP improves the EA’s ride quality better than the NSS-TMD; and the NSS-AP should be used on the seat suspension of the EA to further enhance the ride quality.
