摘要
超高压压缩机脉冲阀螺栓在交变载荷作用下,使用一段时间后可能会产生疲劳失效破坏。文中介绍了脉冲阀螺栓疲劳寿命的分析方法,利用裂纹扩展速率与螺栓的临界裂纹尺寸对含缺陷的螺栓疲劳寿命进行了计算,为设备的诊断维护提供了合理的依据。
The pulse value bolt of super high pressure compressor may get fatigue failure after by action of the alternating loads.The analysis methods of fatigue life to pulse value bolt are introdueed,the fatigue life can calculate according to the rate of crack growth and critical flaw size of bolt material. It provide a reasonable basis to the equipment maintenance.
