摘要
通过力学分析可知泵轴断裂失效类型为高周疲劳 ;通过肉眼宏观观察、金相分析 。
Mechanical analysis tells us that the fracture failure of the pump shaft is of the type of high cycle fatigue It can be concluded that the main causes of the fracture failure of pump shaft are mechanical processing,heat treatment and the material defects after visual macroexamination and metallographic analysis.
