摘　　要：采用三维有限元方法对某厂进口PTA_RPF循环鼓风机叶轮故障进行计算,着重分析了整个叶轮的应力分布和变形。结果表明,叶轮故障的主要原因是轮盖外缘加强圈间断焊缝长度较小引起的。A three dimensional finite element method（FEM） was adopted to calculate impeller failure of an imported PTA_RPF blower,and its stress distribution and distortion were mainly analyzed.The analytical results show that the shorter discontinuous welding line between cover and its reinforcing ring can result in the impeller failure.
