摘要
目前基于GB/T 3077-1999《合金结构钢技术条件》的牵引电机转轴材料性能的评定方法存在一定的局限性,文章针对牵引电机转轴的结构特性和材料特性并考虑实际的载荷工况,从化学成分、机械性能及探伤等方面提出一种合理评定牵引电机转轴材料性能的方法。试验结果表明,该评定方法比现有方法更合理,其为牵引电机转轴的设计选材提供了有益的参考。
At present, there are some limitations in the material evaluation method of shaft for traction motor based on GB/T 3077- 1999 Specification for the Alloy Structure Steels. With a view to the structural characteristics, material properties and actual load condition, a rational evaluation method of the shaft for traction motor was proposed in terms of chemical composition, mechanical properties and flaw detection etc. Test results indicate that this method is more rational than the current one, which can provide more useful reference for the material＇s selection of the shaft.
