已经开发了一个确定动态车辆侧翻临界值的方法,该方法采用一侧翻平面车辆模型和以低速进行试验测量的侧向加速度为基础仿真。然后采用曲线拟合技术推断侧向加速度和前进速度的临界值。该方法采用变通道运动试验证实,并获得一个良好的相互关系。本方法很好适应确定侧翻临界值一目标试验程序,仅需要测量侧向加速度。
A method has been developed to determine the rollover threshold of a dynamic vehicle based on a rollover vehicle model and a lateral acceleration based on experimental measurements at low speeds. Then curve fitting technique is used to infer the critical values of lateral acceleration and forward velocity. The method was demonstrated using a variable channel exercise test and achieved a good correlation. This method is well adapted to determine a rollover threshold-a target test procedure that only requires measurement of lateral acceleration.
