摘　　要：借助有限元软件ALGOR,对大型PTA项目用RPF循环鼓风机叶轮与轴的过盈配合问题进行三维有限元计算分析,针对不同的过盈量和转速进行了计算,获得了叶轮与轴之间接触应力的相应分布规律。这对于确定合理过盈量和改进设计具有参考意义。In virtue of finite element ALGOR software,interference fit of circular blower which application in RPF for large PTA was calculated and analized based on FEM.The effects of fit tolerance and rotational speed,the displacement and the contact stress on the interference-fitting surface were discussed in detail in the numerical computation.The results provided an effective approach which achieved more reliable interference-fitted connections and optimization design for interference.
