train running state

In this paper, the dynamic optimization model is established and the train running state of optimum energy consumption is simulated with the help of computer.

本文采用动态最优化模型，借助计算机对列车运行状态进行模拟，求出其以节能为目标的优化运行方式。

The cargo loading state, such as if the cargo outline intrude the circumscriptions or if the vehicle door is open, has large effects on the running safety of cargo train.

货物装载尺寸是否超限，货车车门的开闭状态直接影响到货物列车的运行安全。为此铁科院铁建所研制了货车装载安全状态监测系统。

Coefficient of derail is used to judge whether a train is in the normal running state or in derail state.

以脱轨系数为依据判断列车能否正常行驶，采用响应面法求解失效概率。
