摘要
采用不确定性方法对车辆制动过程中的随机参数进行了分析。针对制动过程中的瞬时车速以及最大制动力建立可靠性模型,将随机理论和随机摄动技术引入到车辆制动性能分析,利用不确定性理论给出了分析结果的置信区间和置信度,提高了车辆制动性能分析的准确度。与蒙特卡洛随机模拟方法得到的计算结果进行对比,验证了本文方法的正确性和准确性。
Stochastic parameters in vehicle braking process are analyzed by uncertainty theory. According to the braking speed and maximum braking force, the reliability evaluation is established, in which the stochastic theory and proba-bilistic perturbation are introduced. The confidence interval and confidence of the result is given which improves the accuracy of the braking performance analysis. And the result is compared with that of Monte-Carlo which shows its correction and accuracy.
