摘　　要：针对列车牵引计算的特点,先对机车牵引力利用拉格朗日插值公式进行不等距插值,得到任意速度点处的牵引力;然后以距离间隔按近似积分法来解算列车运动方程式。该系统正是基于上述算法,并采用面向对象的Visual C++编程技术开发而成。大量测试数据表明,该系统使用方便、计算结果准确。According to the characteristics of train traction calculation, we firstly obtain the haul force of locomotive at any velocity point using Lagrange formula, and then solve train motion eqution in the light of distance interval by approximative integral method. The system is based on object-oriented programming technique of Visual C++ 6. 0. Many testing data show that the system is convenient to use and the calculated results are accurate.
