摘要
本文是以高速动车转向架构架用耐候钢S355J2W为研究对象,对该耐候钢进行四种不同温度下的模拟火焰矫正实验,在符合材料冷却条件后进行拉伸、弯曲、冲击等力学性能实验,实验结果分析表明,热模拟温度控制在700℃时,材料表现出最佳的综合力学性能。本实验结果对S355J2W耐候钢进行火焰矫正有实际的指导意义。
The paper studies the weathering steel S355J2 W of high-speed train with a bogie frame by simulating flame correction experiment with four different temperatures. In line with the material cooling conditions tensile, bending, impacting and other mechanical properties tests are made.The experimental results show that when thermal simulation temperature is control at 700 ℃, the material exhibits the best mechanical properties. The results have practical significance on weathering steel S355J2 straightening flame.
