为了解决牵引计算中列车出坡速度试凑问题,引入线性查值法计算非特征点下列车的单位合力,在列车运动方程的基础上结合剩余坡段长度建立关于出坡速度的一元二次方程,通过求根公式一次性计算出列车的出坡速度。采用直线模拟列车单位合力曲线,通过积分解算出一种与《列车牵引计算规程》不同的列车运动方程的一般形式,而后引入牛顿迭代法,求解列车的出坡速度。
In order to solve the trial and error problem of trains in the traction calculation, a linear search method is used to calculate the unit force of the trains under the non-traced points. Based on the train equation of motion and the length of the remaining steps, a quadratic quadratic equation , Through the root formula one-time calculation of the train’s ramp rate. A straight line is used to simulate the train unit resultant force curve. By integral solution, a general form of train equation of motion different from that of train traction calculation formula is calculated. Then Newton iteration method is introduced to solve the train’s ramp-down speed.
