Analysis on the Passing of the Curve Profile of Road Transportation for Oversize Cargo Vehicle Group

弯道轮廓通过性分析是大件运输车组安全通过弯道的一个重要方面。本文通过弯道几何条件和车组数据,建立弯道轮廓表达模型和大件运输车组轮廓函数表达式,通过分析弯道轮廓通过性的要求,建立以方向盘转角总和最小为目标函数的大件运输车组安全行驶轨迹优化模型,使用遗传算法求解并运用TruckSim–Simulink进行实例仿真,结果显示大件车组能够安全通过弯道,验证了模型及算法的有效性。

The curve profile passing analysis is an important aspect for oversize cargo vehicle group to pass the curve safely. The curve profile expression model and the contour function expression of oversize cargo vehicle group are established based on the geometric conditions of the curve and the data of the vehicles. Based on the analysis of the requirements of passing curve profile, a safe trajectory optimization model for oversize cargo vehicle group was established with the minimum steering wheel Angle as the objective function. It was solved by genetic algorithm and simulated by Trucksim-Simulink. The simulation results show that oversize cargo vehicle group can pass the curve safely, which verifies the effectiveness of the model and algorithm.
