本文将“局部应力应变法”用于涡轮叶片寿命预测的几个主要环节,经验证明,这个方法是预测构件(不仅限涡轮叶片)寿命的有力工具,无论在设计或确定现有装置的工作可靠性方面,都会起很大作用。最后指出,要实际应用到发动机或其它复杂装置上时,尚有一些障碍(例如载荷谱和应力分析手段的效率和费用)有待解决。 In this paper, the “local stress-strain method” is applied to several key aspects of turbine blade life prediction. Experience has proved that this method is a powerful tool for predicting the life of components (not only turbine blades). Whether designing or confirming the reliability of existing devices Sex, will play a big role. Finally, it is pointed out that there are still some obstacles (such as the efficiency and cost of load spectrum and stress analysis methods) to be solved when actually applied to engines or other complicated devices.
