| 摘 要： | 以叶片榫头进气窗口为结构细节优化对象,基于DD6单晶高温合金再结晶临界应力,通过单晶涡轮叶片铸造残余应力场仿真计算,建立了最大铸造残余应力与结构参数和温度的关系模型.在几何约束和动力约束工况条件下,开展叶片榫头进气窗口结构细节优化研究,最后与实际叶片榫头进气窗口的进行分析与对比.结果表明:优化后叶片榫头进气窗口区域最大铸造残余应力降低20%以上,原有的再结晶现象消除.

| Abstract: | Take the air inlet window of blade tenon as detail-structure optimization object, the relationship model between maximum cast residual stress and structure parameters and temperature were established by the simulation of cast residual stress field of single crystal turbine blade based on the recrystallization critical stress of DD6 single crystal superalloy. The detail-structure optimization of air inlet window of blade tenon was studied under the conditions of geometric and dynamic constraints. Finally, through the analysis and comparison with the actual air window of blade tenon, this method was effectively verified. The results show that the maximum cast residual stress of optimized air inlet window of blade tenon is completely reduced by over 20%, and the recrystallization is effectively eliminated. |
