| 为克服频率响应法对车辆平顺性预测的局限性，建立了8自由度的汽车乘坐动力学模型和随机路面激励的时域模型。乘坐动力学模型考虑了包括坐椅在内的车辆的垂直、俯仰和侧倾3种运动。利用MATLAB／SIMULINK仿真工具对某型车辆在B级路面行驶时的平顺性进行了时域仿真分析。研究结果表明，此方法能够快速地对车辆在随机路面行驶的平顺性进行预测和评价。 |

| Abstract: |
| To overcome the limitation of frequencey responding analysis method, an eight freedom model of vehicle ride dynamic was developed. The model involves the vehicle vibration in vertical, pitching and longitudinal. Computer simulation in time domain of the vehicle ride on B grade road that use the Matlab/Simulink was carried out. The research result showed that this method can be used to evaluate and predict the ride comfort of vehicle running on the random road, it is helpful to design and control the vehicle suspension system. |
