为提高牵引电算中求解列车紧急制动限速的效率,将列车紧急制动工况下的换算制动率、闸瓦换算摩擦系数、列车基本阻力、加算坡度、计算制动距离转换成相应的方程,利用二分法求解列车的紧急制动限速。仿真计算证明,该方法减少了迭代次数,提高了计算精度并取得了良好的时间复杂度。 In order to improve the efficiency of solving the train emergency braking speed limitation in the traction calculation, the conversion braking rate, the friction coefficient converted by the brake shoe, the basic resistance of the train, the added slope and the calculation of the braking distance are converted into corresponding Of the equation, the use of dichotomy solve the train emergency braking speed limit. Simulation results show that this method reduces the number of iterations, improves the calculation accuracy and achieves good time complexity.
