| 摘 要： | 论述了新《牵规》规定的闸瓦摩擦系数制动初速修正项在合力图中的应用问题。指出在编制合力图计算制动工况的列车单位合力时，只选定一个固定制动初速的闸瓦摩擦系数，作出一条该制动初速下的制动合力曲线，只要根据不同制动初速对单位制动力的影响适当移动单位合力的坐标原点，这条合力曲线就可以适用于各种制动初速。

| Abstract: | This paper discussed the problems in the new “Traction Regulations"about the application of the modifying item of the brake shoe friction coefficient and braking initial velocity in the total force figure,pointed out that one constant braking initial velocity and one shoe friction coefficient can be selected in the calculation of the unit total force of the train under the braking case by drawing the total force figure.Therefore,the braking total force curve was done under the same braking initial velocity.This surve can be applied for kinds of braking initial velocity if only moving the position of origin point coordinate according to the initial velocity properly. |
