提出了在多种损伤机理作用下汽轮机部件基于裂纹扩展寿命的制造缺陷安全性评定方法
介绍了汽轮机部件缺陷安全性评定的多种损伤机理。提出了低周疲劳、高周疲劳、蠕变与应力腐蚀等单种损伤机理作用下裂纹扩展寿命及多种损伤机理作用下不同阶段低周疲劳裂纹扩展寿命的计算方法。建立了寿命损伤评价理论模型
构建了汽轮机部件基于裂纹扩展日历寿命、允许初始裂纹尺寸、允许初始缺陷面积的缺陷安全性评定方法。给出了1 000 MW等级核电汽轮机高压转子、低压内缸与低压转子在多种损伤机理作用下缺陷安全性评定的工程应用实例。结果表明:按照传统方法判定报废的缺陷当量直径为2 mm的核电汽轮机转子与汽缸可以安全服役。
A safety assessment methodology was proposed for manufacturing defects in steam turbine components based on crack propagation life under multiple damage mechanisms
and multiple damage mechanisms were introduced for safety assessment of steam turbine components. Calculation methods were presented for the crack propagation life under single damage mechanism (e.g.
low-cycle fatigue
high-cycle fatigue
creep
stress corrosion)
and the low-cycle fatigue crack propagation life at different stages under combined damage mechanisms. Theoretical models of life damage evaluation were established
and based on the crack propagation calendar life
allowable initial crack size
and allowable initial defect area
a safety assessment methodology for defects was constructed. After which
engineering application examples were provided for defect safety assessment of 1 000 MW-class nuclear steam turbine components
including high-pressure rotors
low-pressure inner casings
and low-pressure rotors under multiple damage mechanisms. Results demonstrate that the rotors and casings of nuclear steam turbine containing defects with an equivalent diameter of 2 mm
which are previously classified as unserviceable under conventional assessment criteria
can safely remain in operation.
