- Abstract:
- A combination of the semi-active suspension(SAS)and quasi-zero stiffness structure(QZSS)is proposed for a seat suspension to improve the ride comfort of a vibratory roller. A 3D vehicle dynamic model is built to assess the isolation performance of the seat’s SAS combined with the QZSS under a vehicle’s different working conditions on elastoplastic soil. An experimental investigation is also used to verify the accuracy of the model. The weighted root mean square(aws)and power-spectral-density(PSD)accelerations of the driver’s seat are selected as the evaluation indexes. The research results show that the seat’s SAS significantly improves the vibratory roller’s ride comfort compared to the seat’s passive suspension(PS), whereas the QZSS added into the seat’s PS improves the ride comfort better than the seat’s SAS. In particular, with the QZSS embedded in the seat’s SAS, the values of aws and the maximum PSD of the driver’s seat are strongly reduced by 75.7% and 74.3% compared to the seat’s PS, respectively. Therefore, the QZSS embedded in the seat’s SAS should be used to further enhance the ride comfort of the vibratory roller.
