高温紧固螺栓的剩余寿命评估
摘要
提出了一种评估高温紧固螺栓剩余寿命的计算模型
并对一实际螺栓进行了具体计算
在此基础上分析了装配、运行及材料性能等因素对螺栓蠕变和疲劳损伤的影响。
Abstract
A calculation model for evaluating the residucal service life of hightemperature fastening bolts has been put forward
and concrete computation of a real bolt being carried out. On this basis
the influence of some factors
such as installation
operation
and material’s behavior etc.
upon bolt’s creepage and fatigue damage has been analysed.
