| 摘 要： | 运用多刚体动力学罗伯森-维登堡法,建立了六自由度铰接式自卸车操纵稳定性模型.用MATLAB计算出XAD250型铰接式自卸车满载与空载时的横摆角速度增益曲线,得出空载时具有较大的不足转向特性.使用该模型进一步计算了轮胎侧偏刚度、后节质心布置以及悬架系统参数等,以便研究它们对铰接式自卸车操纵稳定性的影响.

| Abstract: | A 6-DOF rigid multi-body handling stability model of an articulated dump truck (ADT) was developed by Roberson-Wittenburg method. XAD250 yaw velocity gain curves under no-load and full-load states were calculated with the software MATLAB. From the curves it was found that the no-load ADT had larger under steer than the full-load one. Some parameters were calculated such as tire lateral stiffness, centroid position of every segment, and suspension system parameter, which influence the handling stability of an ADT. |
