摘要
为检验涡轮机叶片材料及其结构能否适应高温工作环境,分析了叶片根部的应力分布情况,并对复速级涡轮机的二级叶片的强度进行了校核,给出了叶片根部关键点的安全系数,确定了叶根的危险点,探讨了叶片中径对叶片根部的应力的影响规律。
In order to confirm the suitable function of material and structure of vanes in the high temperature condition, it analyzes the stress distribution of blade root, checks the stress intensity of vanes of 2 - stage turbine, gives out the safety factor of keypoints in blade root, and affirms the hazardous point, discusses the influence of average diameter of vanes to the stress of blade root.
