摘　　要：针对HXD1型机车在大秦线上运行时渡板碰撞问题进行研究。对于机车在曲线上的危险工况,采用叠加法分析了重联机车过小半径曲线时的状态,分析了渡板发生大的相对横向位移的原因。根据分析结果归纳出影响渡板碰撞的4点主要因素,并且采用"渡板碰撞特征曲线"来分析渡板的碰撞。最后针对这4点影响因素提出了渡板改造方案,实际运行证明,改造后渡板碰撞概率大为降低。This paper studies the problem of cross apron collision of HXD1 locomotive running on Daqin railways. The risk status of double-heading locomotive passing sharp radius curve has been analyzed by superposed method. The reason of large transverse displacement of cross apron is also analyzed. Bases on the results, four effect factors of the collision have been reached. The figure of ＇impact characteristics between cross apron＇ is adopted to analyze the collision of cross apron. During actual running, the probability of cross apron collision has been reduced rapidly.
