摘要
结合高压空气瓶疲劳失效现象进行有限元应力分析和断口分析,研究高压空气瓶疲劳失效的主要原因。通过验证性循环疲劳试验,表明增加高压空气瓶内表面应力集中部位的表面无损检测和缺陷消除能够提高高压空气瓶的耐疲劳性能,对高压空气瓶的安全使用具有重要意义。
Finite element stress analysis and fracture analysis has been combined with high pressure air cylinder fatigue failure phenomenon,and used to study main reason for the fatigue failure. By confirmatory cycle fatigue tested,it shows increasing the surface non-destructive testing and defect elimination at air cylinder stress concentration surface can improve fatigue resistance,and it is important for the safe use of high pressure air cylinder.
