汽轮机叶片的调频可靠度统计分析
A Statistical Analysis on the R(?)liability of Turbine Blading Vibration Frequency Regulation Using the Established Data Base
【摘要】 利用已建立的叶片频率数据库内的数据,对上海汽轮机厂生产的125MW和300MW汽轮机的各级调频叶片的实测频率进行定量的调频可靠度分析,并以此来评价各级叶片的调频安全性,同时也对上海汽轮机厂改进前、后生产的产品进行可靠度比较。
【Abstract】 A reliability analysis on. the measured values of blading vibration freqency in SSTM (ShanghaiSteam Turbine Manufacturing CO.) Manufactured 125 and 300MW turbine by using the established data basewas carried out. thus the safety of the biading frequency is evaluated and a reliability comparison of theSSTM Products before and after Modification is made in thes paper.
