摘要
以高速车辆单边通过障碍发生事故为背景,利用动力学理论与方法对车辆通过单边障碍过程的行驶特性进行了系统分析,建立数学模型。结合系统理论,建立车辆单边通过障碍时的行驶特性方程及过程分析数学表达式。运用数学计算工具对不同事故状态进行了数值计算分析,绘制了相关图形。分析结果表明障碍参数不同,发生事故的临界数值不同。该结果为车辆单边通过障碍侧翻事故预防提供了理论依据和研究基础,具有较高的实用价值。
Based on the accident that the vehicle rolls over when rapidly passing the unilateral - obstruction, with the kinetic theory and method, the running trait of the process is analyzed by the numbers that the vehicle passes through the unilateral -obstruction, and the bifurcation modeling is established. Combining with the system theory, the equation of the running trait and the mathematical expression of the process that vehi- cle passes the unilateral -obstruction is established and analyzed. Using the calculating tools, the numerical values from each state of the accident are calculated and analyzed, and the correlative figures are also drawn. The results indicate that if the parameters of the obstruction change, the critical numerical values differ. The result is of high practical value to provide the theory and study foundation for preventing the accident that ve- hicles roll over when passing the unilateral obstruction.
