重型燃气轮机涡轮叶片寿命分析研究进展

摘要

本文综述了重型燃气轮机涡轮叶片的材料和冷却技术研究进展，涡轮叶片寿命国内外研究现状，以及疲劳寿命预测方法和蠕变寿命预测方法。总结了国内外燃气轮机叶片寿命分析方面的研究成果，对未来涡轮叶片寿命研究的发展趋势进行了初步展望，旨在为该方向研究提供帮助。%A summary of three questions about heavy-duty gas turbine is reviewed in this paper, they are the research progress of mate-rials and cooling technology of turbine blades, the research status of turbine blades life at home and abroad and prediction method of the fatigue life and the creep life.The results of researching gas turbine blades at home and abroad are summarized in this paper, and it conducts preliminary outlooks for tendency about study of turbine blades life in the future, which are expected to help for the research of this issue.
