铁路应用 - 制动性能的计算（停止 减速和静止制动） - 第2部分:一般算法利用一步一步的计算

[中文适用范围]： 本文件规定了铁路机车车辆制动性能的计算方法。 本文件描述了使用瞬时值输入来执行制动设备和制动性能计算的通用算法/公式，包括所有类型轨道车辆（作为车辆或单元）的停止/减速距离、制动功率和能量。 计算可以在铁路机车车辆评估过程（设计、制造、测试、验证、调查等）的任何阶段进行。 本文件没有规定具体的验收标准（通过/失败）。 本文件无意用作制动系统选择的设计指南，也不规定性能要求。 本文件没有提供计算当所需附着力水平超过可用附着力（车轮滑动活动）时停止距离延长的方法。 本文件包含不同制动设备类型的制动力计算示例以及车辆或单元的停车距离计算示例。 [外文原描述]： This document specifies the methodologies for calculation of braking performance for railway rolling stock. This document describes the general algorithms/formulae using instantaneous value inputs to perform calculations of brake equipment and braking performance, in terms of stopping/slowing distances, braking power and energy for all types of rolling stock, either as vehicles or units. The calculations can be performed at any stage of the assessment process (design, manufacture, testing, verification, investigation, etc.) of railway rolling stock. This document does not set out specific acceptance criteria (pass/fail). This document is not intended to be used as a design guide for the selection of brake systems and does not specify performance requirements. This document does not provide a method to calculate the extension of stopping distances when the level of demanded adhesion exceeds the available adhesion (wheel slide activity). This document contains examples of the calculation of brake forces for different brake equipment types and examples of the calculation of stopping distance for vehicles or units.
