威斯汀豪斯公司根据多年试验积累的制动性能方面的资料,编制了模拟车辆制动的计算程序,该程序为计算车辆制动和分析制动的各种因素提供了实际而有效的方法。影响车辆制动性能的因素影响车辆制动性能的因素主要分为两类:制动期间保持不变的因素(机车车辆的重量、列车的长度、车辆制动机类型、闸瓦型式等)和制动期间变化的因素(如制动缸压力、摩擦系数、车轮踏面温度、基础制动效率、列车或车辆阻力、线路坡度、动力制动等)。
Based on years of accumulated test braking performance information, Westinghouse has developed a computational program to simulate vehicle braking which provides a practical and effective method of calculating vehicle braking and analyzing various factors of braking . Factors that Affect Vehicle Braking Performance The factors that affect vehicle braking performance fall into two main categories: the factors that remain constant during braking (the weight of the rolling stock, the length of the train, the type of vehicle brake, the type of brake shoe, etc.) and Factors that change during braking (eg brake cylinder pressure, friction coefficient, wheel tread temperature, basic braking efficiency, train or vehicle resistance, line slope, dynamic braking, etc.).
