煤炭运输除铁路外,公路运输占有很大比重,而在运输过程中,车辆转弯时不仅要考虑车上煤炭的移动,而且要考虑周围行人的安全。文章从安全转弯角度出发,建立数学模型,探究转弯的轨迹曲线,进一步明确车辆转弯时行人应保持的安全距离范围的计算方法,应用Matlab软件模拟仿真,并通过实际车型数据进行对比验证,得出相对精确的计算结果,同时提出避免出现事故的合理建议。 In addition to the railway transport of coal, road transport account for a large proportion, and in the transport process, the vehicle turns not only to consider the movement of coal in the car, but also to consider the safety of pedestrians around. From the perspective of safety turning, this paper establishes a mathematical model, explores the trajectory curve of turning, further clarifies the calculation method of the safe distance range that pedestrians should keep when the vehicle turns, applies Matlab software to simulate the simulation and compares with the actual vehicle type data to draw the conclusion Relatively accurate calculation results, while putting forward reasonable suggestions to avoid accidents.
