摘要
使用有限元软件ANSYS/FLOTRAN CDF对某型燃气轮机篦齿封严装置进行了分析,探讨了篦齿封严的原理,同时分析了齿顶宽与齿隙之比对封严效果的影响,提出了在篦齿封严装置设计制造过程中应注意的问题。
Analyzing the labyrinth seal in the ges turbine engine with finite element software ANSYS/FLOTRAN CD. Fundamentals of Labyrinth seal was dicussed,and the effeet on labyrinth seal by relative sealing clearance was analyzed. Finally, some method of improving labyrinth seal was got in devising and producing.
