分析法求解避难线长度的探讨

DISCUSSION ON SOLVING THE LENGTH OF REFUGE SIDING BY ANALYSIS METHOD

本文通过分析列车进行避难线的运动状态及特点，抓住了避难线长度只与列车始终状态有关，而与列车运行过程无关的本质，二次运用能量守恒原理，找到了求解避难线长度的关系式，经算例检算是精确的，且方法简便。

The paper analyzes the moving state and the characters of the train running into the refuge siding.The length of the refuge siding will be deternuned by the initial state and the final state of the train,no matter what's the running procedure of the train.By applying twice the law of conservation of energy, the relative equation for solving the length of the refuge siding has been found. Checked by the calculating examples, the results are accurate and the method is simple and comvenient.
