本文利用能量方法研究车辆的侧翻性能，提出了一种新的车辆侧翻稳定性综合评价方法。建立了复杂非线性十自由度车辆动力学模型，并通过试验验证了模型的正确性。定义了车辆侧翻能量稳定指标：通过计算车辆实时能量储备与车辆侧翻的能量阈值比值得到侧翻能量储备系数，整合车速和转向输入得到车速-转向干扰系数，最终建立一个包含车速、侧倾角速度、侧倾角和轮胎转角等因素的车辆侧翻稳定性综合评价指标。最后在十自由度车辆动力学模型的基础上进行多工况仿真实验，通过与现有评价指标的对比分析，验证了该评价指标的正确性和适用性。
Abstract
The energy approach is applied to study on the vehicle rollover-stability, and a new comprehensive evaluation method for vehicle rollover-stability is proposed. In order to study this methodology, a 10-DOF vehicle model with nonlinear characteristic is presented, and the comparison of vehicle road test and simulations with vehicle model verified that the model is correct. The rollover-stability index is provided: By calculating the ratio of real-time energy reserve and rollover energy threshold, the rollover energy reserve coefficient (RERC) can be deduced. And the velocity-steering interference coefficient (VSIC) is defined by integrating the vehicle velocity and the steering angle. After then, the comprehensive evaluation index of vehicle rollover stability, which contains the vehicle velocity, roll angle velocity, roll angle and tire steering angle, is established. Furthermore, the presented method is compared with the other vehicle rollover-stability evaluation method by different situation simulation experiments. The result shows that the presented method is correct and applicability.
