永磁直驱转向架可使用模块化设计式,试制过程必然会出现很多焊接变形控制的问题,其中最重要的问题就是构架组装工序,特别容易出现侧梁两端中心距的尺寸超出范围,不能达到工艺的要求和标准;本文是对焊接的顺序和工艺流程给出不断优化和改进的方法,从而使之不仅能够达到质量标准,还能满足工艺的要求。
Permanent magnet direct-driven bogie can be used modular design, the trial production process will inevitably appear a lot of welding deformation control problems, one of the most important issue is the frame assembly process, particularly prone to the size of both ends of the side beams out of range size, can not To meet the requirements and standards of the process; This article is to continuously optimize and improve the welding sequence and process, so that it can not only meet the quality standards, but also meet the requirements of the process.
