摘要
列车制动过程中,车轮荷载作为移动荷载作用于线路和桥梁结构.若要深入研究移动车轮产生的制动力时程对线桥结构的影响,必须将其离散到钢轨各节点处,即将轮对的制动力时程转换为轨面节点的制动力时程.文中阐述了列车制动力的这种离散分析方法,以及它在制动力有效系数研究上的应用.
In course of train＇s braking, wheel load bring pressure to track and bridge structure qua locomotive load. studying home braking time history＇s influence on structure which is generated by locomotive wheel, we must disperse on each node of rail surface, namely transforming wheel＇s braking force time history into node braking force time history rail surface. This paper expound this disperse analysis method of train braking force, along with its application to study braking force effective coefficient.
