Life Prediction for Turbine Disc by Monte-Carlor Method
-
摘要: 部件壽命預測過程中應根據部件運行經濟效益最佳的原則選擇壽命預測置信度,由此可避免因置信度太高而導致大量部件尚可使用就被更換,或置信度太低而出現大量的突發性事故.利用Monte-Carlor方法討論了GH132合金煙機渦輪盤的最佳設計壽命.Abstract: To avoid unnecessory retirement or unexpected failure of large components operating at elevated temperature, a method is recommended to choose a reasonabl value of confidence of life predition for components. Monte-Carior method is used to estimate the lifehme of discs used in oil refinery power recovery gas expanders.
