摘要
转向架是动力机车的最重要的承载结构,其焊接变形预测对于保证加工精度和质量具有重要意义.首先通过大量的计算和实测建立了转向架结构的固有应变数据库,然后运用基于固有应变的弹性有限元分析的焊接变形预测专用软件WSDP对六轴式转向架侧梁焊接变形进行预测,预测结果与试验数据具有很好的一致性,所建立的固有变形数据库的可靠性得到验证,研究表明WSDP软件是大型复杂结构的焊接变形预测的有力工具.
The bogie frame is the most important bearing structure of the locomotive,and its prediction of welding deformation has important significance in ensuring manufacturing accuracy and quality.First,the database of inherent strain for bogie frame structure was established by a lot of computing and practical measure.Then the welding deformation of hexad-axled locomotive bogie frame side-beam was predicted by using software WSDP (welding structure deformation prediction),which is based on the theory of inherent strain and elastic finite element model.The results were totally consistent with experimental data,and the reliability of the database was proved.The study shows WSDP is very useful in welding deformation prediction of large and complex structures.
