摘要
基于国际焊接学会标准和英国标准,结合有限元静强度结果和实测载荷谱,对某出口运煤车车体关键部位典型焊接接头形式进行了疲劳寿命对比分析。结果表明,合理选择焊接接头形式和焊接工艺可以成倍地提高结构的疲劳寿命。
According to standards of the International Welding Society and British Standards,with the finite elements static strength results and the actually measured load spectrum,the fatigue life comparison analysis is made for the modes of typical welded joints at key parts of an exported coal car body.The results show that the proper selection of modes of welded joints and welding technologies can double improve the fatigue life of structures.
