| 摘 要： | 运用动静法创建了稳态回转时五连杆后悬架的侧倾平面模型运动方程,运用矢量几何法分析了车体侧倾角和横向推力杆方向角之间的关系。通过对某SUV车实例分析,得出了不同的几何位置下车体侧倾角、有效侧倾刚度及侧倾中心位置的变化。结果表明,当车辆稳态回转时,横向推力杆的长度及方向角、上拉杆的布置对悬架的侧倾特性有重要影响;仿真结果与道路试验结果在趋势上有较好的一致性。 |
| 关 键 词： | 非独立后悬架 五连杆 侧倾性能 |

| Abstract: | The rear suspension roll plane kinematics equations during steady state turning are established by means of kinetostatic method.The relation of the roll angle and the lateral rod direction angle is studied with the vector geometric method.With case study of a SUV,the change of roll angle,effective roll stiffness and central position of roll under different geometrical locations is obtained The results of the study show that during steady turning,length of lateral rod,direction angle,arrangement of upper link affect roll characteristic of suspension significantly;the simulation results are identical with road test results. |
| Keywords: | Dependent rear suspension Five-rod Roll performance |
