| 摘 要： | 通过对铰接车辆横向一级失稳过程的微分推导，求出了失稳过程中整机质心运动轨迹在起始点处的切线矢量，利用该矢量可以计算车辆在不同停机方位的失稳坡角度。该方法不依靠横向一级倾翻轴来计算同一级失稳坡角度，否定了传统横向一级稳定性理论中“摆动桥不参与横向一级失稳”的观点，指出了用横向一有倾翻轴计算稳定性的片面性，为准确计算横向一级稳定性奠定了基础。铰接车辆模型试验的结果验证了本文理论分析的正确性。

| Abstract: | In this paper, the tangent vector in the startpoint of the motion path of the vehicle's mass center during the unstability process was extracted by differentiation analysis of the first order lateral overturning process of articulated vehicle, and by using it, the unstable slope angle in different parking site can be calculated. This method calculates the first order unstable slope angle not according to the first order lateral overturning axle, and negates the standpoint that pendulum axle not participates in the first order lateral unstability process in traditional theory of the first order lateral stability, and refers to the one sidedness to calculate the stability by the first order lateral overturning axle. This method also forms the fundament of calculating the first order lateral stability accurately. The theoretical analysis has been proved by the model experimental results. |
