| 摘 要： | 牵引加速度计算是列车牵引制动特性计算过程中的重要组成部分。因为无显式计算公式，实际计算中一般采用数值计算方法。不同的数值计算方法和不同的计算步长，将导致最终的结果与真实值之间存在不同的误差。文章通过对比不同的数值计算方法。分析这些方法的异同。

| Abstract: | Traction acceleration calculation is one of the most important components of the traction and braking characteristic computation of the train . Because there is no obvious compute formula,it is always done by numeric calculation. Different numeric calculation methods and different calculation steps will cause outcomes have different calculation errors. Through comparing different numeric calculation methods ,this article has analyzed the similarities and differences of them. |
