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.
为了提高振动压路机的平顺性, 提出了一种座椅悬架的半主动悬架(SAS)和准零刚度结构(QZSS)的组合.建立了3-D振动压路机的动力学模型, 在弹塑性土壤各种工作条件下, 对座椅的SAS和QZSS进行仿真与性能分析.将驾驶员座椅的加权加速度均方根值(aws)和功率谱密度加速度(PSD)作为目标函数, 进行了试验研究, 以验证模型的准确性.研究结果表明, 与座椅的被动悬架相比, 座椅的SAS显著提高了振动压路机的平顺性, 而座椅被动悬架中添加QZSS比座椅的SAS更能提高平顺性.特别是QZSS添加在座椅SAS中, 驾驶员座椅的aws和最大PSD值相比座椅的被动悬架分别降低了75.7%和74.3%.因此, 将QZSS添加在座椅SAS中, 可以进一步提高振动压路机的平顺性.
