离心式压缩机叶轮的结构与应力

Structure and Stress for Centrifugal Compnessor Impeller

评述了叶轮与应力分布的关系，提出了在轴盘上使用“导力锥”可以对轴盘的强度及转子进行临界转速调控的新观念，并研究了轮盖应力和叶片进口斜角的关系及叶轮的最大应力点也可以出现在轴盘上的条件与原因。

The relationship between the impeller and the stress distribution is reviewed;a new concept which uses guide cone at the shaft disk to carry out the shaft disk strength control and to carry out rotor critical speed control.The relationship between the shroud stress and blade inlet edge bevel angle is studied,and the conditions and reasons about the maximum stress point occurring at the shaft disk are discussed.
