B级铸钢侧架疲劳试验方案研讨

摘要

通过对B级钢与ZG25材料性能的比较、侧架原试验标准的分析、B级钢侧架的寿命估算等研究，就侧架在B级钢下的疲劳试验方案进行了研讨，所得结果可供有关部门参考。%The fatigue test program for side frame of grade B steel isresearched and discussed by means of comparing material performances of grade B steel and ZG25,analyzing original test standard of side frame and estimating service l ife of side frams of grade B steel.The result in this paper can be referred to by related departments.
