研究了已使用11年的超高压聚乙烯反应管材料AISI 4340钢的疲劳强度,通过试验给出了不同应力水平下的疲劳寿命曲线.从而得出了AISI 4340钢的疲劳设计曲线,为在役超高压聚乙烯反应管的疲劳寿命估算提供了数据.
The fatigue strength of AISI 4340 steel, which has been used for 11 years, has been studied, and the fatigue life curves under different stress levels have been obtained through experiments, thus the fatigue design curve of AISI 4340 steel has been obtained, Estimates of fatigue life for UHP polyethylene reactors provide data.
