BS EN 14531-2:2015描述了利用时间步长积分计算制动性能的分步方法，该方法可用于所有类型的列车组、单元或单车，包括高速列车、机车和客车、常规车辆和货车。本欧洲标准未规定性能要求。它可以计算性能的各个方面:停车或减速距离、附着力要求、力计算等。本欧洲标准可以通过计算在高速和常规基础设施上运行的高速和常规列车的停车和减速性能进行验证。它还可用于任何设计/验证阶段的停车或减速性能详细调查。本标准提出的方法基于数值时间积分算法。该标准解释了一个简单的数值积分方案，以便为所提出的方法提供一个有用的简单示例。 存在其他数值时间积分算法，尤其是更精确的算法，但它们不在本标准的范围内。使用此类方法时，其精度顺序必须符合本欧洲标准。本附录EN-1572EN-1342-1中包含了本标准的最新修订版EN-1572EN-1342:2004。本附录EN-1572EN-1672EN-1672EN-16567:1中还包括了本标准的所有其他示例。

BS EN 14531-2:2015 describes the step-by-step method for the calculation of brake performance utilizing time step integration which may be used for all types of train sets, units or single vehicles, including high-speed, locomotive and passenger coaches, conventional vehicles and wagons.This European Standard does not specify the performance requirements. It enables the calculation of the various aspects of the performance: stopping or slowing distances, adhesion requirements, force calculations, etc.This European Standard enables the verification by calculation of the stopping and slowing performance for high-speed and conventional trains operating on high-speed and conventional infrastructure. It may also be used for the detailed investigation of stopping or slowing performance at any design/verification stage.The proposed method of this standard is based on a numerical time integration algorithm. The standard explains a simple numerical integration scheme in order to provide a useful straightforward example of the proposed method. Other numerical time integration algorithms exist, especially more accurate ones, but they are not in the scope of this standard.When such methods are used the order of accuracy that they achieve has to be in accordance with this European Standard.This European Standard also includes examples of distance and other dynamic calculations, see Annex B.Cross References:EN 14067-4EN 14478EN 14531-1EN 14067-1:2003EN 13452-1:2003EN 13452-2:2003EN 15663EN 15734-1EN 15734-2prEN 15328EN 16185All current amendments available at time of purchase are included with the purchase of this document.
