摘　　要：采用ANSYS软件对三维复杂形状宝石窗与可伐封接件在焊接过程中产生的应力进行分析,裂纹位置、形式与模拟的应力结果一致。在数值模拟分析基础上,优化封接结构,改进工艺,封接取得了成功。The seal stress of three dimensions complex shape sapphire window and kovar sealing parts was analyzed by ANSYS software. The form and place of crack was consistent with the result of stress simulation. On the basis of numerical simulation, sealing structure was optimized, the technique was improved and the sealing process was succeeded.
