摘　　要：将压力容器承受的实际变幅载荷历史分解为恒幅块载荷谱的方法称为循环计数方法。介绍了ASME规范推荐的雨流计数法、最大-最小计数法和欧盟标准的蓄水池法。A method breaking a real variable amplitude loading applied to pressure vessels down into a load - spectrum of constant amplitude blocks is called ＂cycle counting method＂. The rainflow cycle count- ing method and max - min cycle counting method recommended both by ASME Code as well as the reservoir method recommended by EN Standard are introduced in this paper.

关 键 词：循环计数方法 疲劳分析 变幅载荷 ASME规范 欧盟标准
