摘要
在研究混流式水轮机转轮结构及其裂纹出现部位的基础上,分析了产生裂纹的原因。同时,探讨了水轮机转轮焊接过程中的温度场和应力场的有限元分析模型及其分析方法。
Based on research on the structure of francis turbine runner and parts with cracks, the reasons of cracks are analyzed. Meanwhile, the finite element model and analysis of temperature field and stress field during the period of welding are discussed.
