摘要
Abstract
The end wall is an important part of the aluminum alloy car body in High-speed EMU.It has a complex construction,amount of accessories and large quantity of welding,all of which may induce the large welding deformation.Welding deformation is caused by uneven heating and cooling during welding.However,the deformation of aluminum alloy is large,which affects the manufacture and performance of welded structure.In this paper,the end wall of a standard EMU is taken as the research object,by adopting the appropriate tooling optimization,assembly process and reasonable welding sequence in the production and manufacture of the end wall,its welding deformation was well controlled,and so its flatness and profile.This reduced the intensity of working adjustment on end wall,improved production effficiency,and met the requirement of mass production.Moreover,the control method in this paper has a good reference significance for other EMU end wall manufacture,and has good value in popularizing.关键词
