摘　　要：介绍了CAE方法在直升机旋翼系统强度结构设计中的仿真应用情况。针对旋转部件的载荷和结构特点,在多年工程设计经验的基础上,建立了一套有限元分析模型和应力计算流程,通过专用程序处理,实现了部件应力分布的可视化显示。最后讨论了此方法的扩展应用。This article introduced a simulation of helicopter rotor part strength design by CAE. Due to the peculiarity with rotating structures and loads applied on them, based on experience of engi- neering practice, conformed a program of finite element model building and stress analyzing. By a special process to identify critical area of part while visualizing them. The extending applications were discussed.
