“…The vibratory roller has been designed with a vibratory drum, two elastic tires, front floor, engine and rear floor, cabin, and driver's seat. [3][4][5][6][7]12,13,23 The vibratory drum is connected with the front floor of the vehicle via the drum isolations, and the vibratory drum is used to create the compression force to compress the deformable terrains. Front and rear floors are connected via the articulation joint.…”

“…[1][2][3][4][5] Besides, researchers are also constantly developing new isolation systems for the cabin and seat to reduce the vibration of both the cabin and seat. [6][7][8][9] In the traveling and compacting conditions of vibratory rollers on deformable soil grounds, the vibratory roller's excitations were directly generated by the tire and vibratory drum interacting with the deformed soil grounds. All these vibration excitations were then transmitted to the driver through isolation systems of the cabin and seat.…”

“…2,3,[10][11][12][13] Therefore, to ensure the ride quality of the driver, with the isolation systems of the cabin and seat, their various models and structures are always studied and developed for isolating the vehicle's vibration excitations. 6,7,13,14 In the development process of isolation systems of the vibratory roller cabin, firstly, the traditional-rubber isolations (TRIs) using rubber materials were designed and applied. The structure of TRIs was also optimized to improve its isolation performance.…”

Besides, from the analysis result of isolation systems of the cabin and seat, the research also gives some comments on the development trend of modern isolation systems.…”

“…6,8,12,17,18 In addition, under the interaction of the tire and random road surface when the vibratory roller is traveling and compacting, the vehicle's ride comfort was remarkably influenced. [4][5][6][7][8] The vibration investigations of vehicles showed that when the vehicle is traveling on a rigid road surface, both indexes of the ride comfort and noise are strongly influenced. 15,[26][27][28] To reduce the vibration and noise generated by the contact of elastic tires and random road surfaces, various models of the tire-road contact such as the point-contact model, roller-contact model, fixedfootprint-contact model, radial-spring-contact model, flexible-ring-contact model, and finite-element-contact model had been proposed to optimize the dynamic force of the tire and road surface interaction.…”

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.

This study proposes the seat’s three isolation systems including the three parallel isolations (TPI), the quasi-zero stiffness structure (QSS) embedded in the seat’s isolation system, and a combination of the QSS and TPI (QSS-TPI) for ameliorating the ride quality of the driver. From the dynamic models of the TPI, QSS, and QSS-TPI established, their parameters are optimized and simulated to compare the performance between the TPI, QSS, and QSS-TPI in isolating the driver’s vibration. The root mean square values of the vertical acceleration ( azs), pitching acceleration ( aφs), and rolling acceleration ( aθs) of the seat have been selected as the objective functions. With optimized parameters of TPI, QSS, and QSS-TPI optimized, the research results show that the vertical acceleration of the seat using the optimized QSS is lower than that of the optimized TPI, conversely, both the pitching and rolling seat accelerations using the optimized TPI have been strongly decreased compared to the optimized QSS. With the optimized QSS-TPI, the azs is greatly reduced by 55.84% in comparison with the optimized TPI while both the aφs and aθs are strongly decreased by 98.76% and 98.46% compared to the optimized QSS. This means that the seat’s QSS-TPI ameliorate the driver’s ride quality and shaking better than that of both the seat’s TPI and QSS. From the simple structure and isolation performance of the QSS-TPI proposed, the seat’s QSS-TPI should be applied to the seat’s isolation system to ameliorate the driver’s ride quality.

In this paper, the experimental study of the asphalt paver is performed to assess the effect of the vibrational screed system’s operating parameters on the asphalt paver’s working performance. Then, the nonlinear dynamic models of the vibrational screed system and tamper system are built to assess in detail the effect of the working parameters of the vibrational screed system and optimise its working parameters to ameliorate the asphalt paver’s working performance. Both the vertical acceleration and angular acceleration of the vibrational screed system computed via their Root Mean Square ( RMS a) value have been selected as the evaluation indexes. Results showed that the acceleration at the measured points has been unevenly distributed on the vibrational screed system’s length, thus, the working performance of the asphalt paver is quite low. With the vibrational screed system’s working parameters optimised, the average value of RMS a with optimisation is increased by 7.67% whereas the average deviation of RMS a between the measurement points with optimisation is greatly reduced by 34.2% in comparison without optimisation. Consequently, the working performance of the asphalt paver has obviously ameliorated.
