摘　　要：枕梁作为轨道交通列车的关键部件,是列车车体与转向架连接的平台,它不仅要承受整车质量,还要承担并传递转向架与车体之间的垂向力、纵向力、横向力,同时兼作空气弹簧的附加气室,其制造工艺流程、工艺方法以及关键部位尺寸控制精度直接影响整车的制造质量。概述了枕梁的制造工艺流程,并结合现场实际生产经验对相关问题进行了归纳总结,探讨了快速市域动车组枕梁的焊接制造工艺以及注意事项,并对出现的常见问题提出了相应的解决措施,进而达到控制枕梁焊后整体尺寸和质量的目的,为后续市域车枕梁的焊接提供了有益参考。As the key part of rail transit train,pillow beam is the platform connecting the train body and bogie.It should not only bear the weight of the vehicle,but also bear and transfer the vertical force,longitudinal force and transverse force between the bogie and the car body.At the same time,the pillow beam is also the additional air chamber of the air spring.Its manufacturing process,process methods and the precision of the key parts of the size control directly affect the manufacturing quality of the vehicle.This paper briefly summarizes the corbel manufacturing process,and connecting with the actual production experience,has carried on the induction summary to related issues discussed quickly reach the EMU corbel manufacturing process and matters needing attention,and the common problems in the corresponding solution measures are put forward,so as to achieve the purpose of controlling the overall size and quality of the pillow beam after welding.It provides useful reference for the production and manufacture of pillow beam in the following market.
