摘要
本文根据焊接结构的疲劳特点和国外对焊接结构疲劳特性的研究成果，借鉴《钢结构疲劳设计规范》￣［２］的计算方法（简称为ＥＣＣＳ规范方法），对２０９型转向架焊接构架进行了疲劳强度评估，并用铁道部四方车辆研究所对２０９型转向架焊接构架的疲劳试验数据作了验证。研究表明，ＥＣＣＳ规范方法用于车辆焊接转向架承载构件的疲劳强度评估是可行的。
On the basis of the fatigue characteristics of welded structures and the achievements in the research abroad, with the reference of the calculation method in the Recommendations for the Fatigue Design of Steel Strcrtures (abbreviated: ECCS Recommendation Method) ,the fatigue strength of welded frames on bogies 209 is evaluated and estimated ,and it is testified with the fatigue teat data of welded frames on bogies 209 provided by Sifang Rolling Stock Research Institute. MOR. The study shows that it is feasible to apply ECCS Recommendation Method to the evaluation and estimation of the fatigue strength of the load carrying parts on welded bogies.
