摘要

以动车转向架常用S355J2+N厚板为研究对象

针对转向架构架制造完成后中厚板出现母材缺陷进行焊接修复后的性能研究。制作模拟修复接头并对其进行拉伸试验、弯曲试验、冲击试验和硬度检测

并对修复后的转向架部件进行静强度及疲劳强度试验验证。结果证明

转向架部件焊接修复后的性能完全能够满足标准要求

为实际生产中的焊接修复作业提供了理论依据。

Abstract

The S355 J2 + N thick plate commonly used in EMU bogies is taken as the research object

aiming at the defects of the base metal of the thick plate after the completion of bogie frame manufacturing

the performance research after welding repair is carried out. The simulated repair joints are made and the tensile test

bending test

impact test and hardness test are carried out on these joints

and the static strength and fatigue strength test verification are also carried out on the repaired bogie parts. The results show that the performance of the bogie parts after welding repair can fully meet the requirements of the standards

providing theoretical basis for the welding repair operation in actual production.
