摘　　要：针对某型船用柴油机高压油管接头断裂事故,采用有限元仿真与试验相结合的方法,研究高压油管接头在冷镦成型过程中的材质的流线型以及内孔的尺寸。通过仿真与试验相结合的方法,研究了冷镦管胚进料长度尺寸对成型材质流线及内孔尺寸的影响,然后探讨了冷镦次数对成型结果的影响,为高压油管接头冷镦成型方案的改进提供了很好的参考。For the rupture of high pressure fuel pipe joint of a marine diesel engine, finite element method and experiment were combined to study the material streamline and the inner hole size of the fuel pipe in the cold heading process. The effect of the feeding length on the material streamline and the inner hole size was studied, and the effect of cold heading times on the shaping result was discussed, which provides a good reference for the development of the cold heading process.
