摘要
介绍了主蒸汽管道的以持久强度试验为主的综合分析法、蠕变曲线逐步外推法和基于蠕变-疲劳损伤的方法等几种剩余寿命预测方法,并对相关方法做了简要评述。
This article introduced three residual life prediction methods of the main steam pipeline.These methods mainly include comprehensive analytic method based on endurance strength,gradual extrapolation method based on creep curves and the prediction method based on creep-fatigue damage analysis.Then it gave brief commentary to these methods.
