提出了整体叶轮一体化保形设计的方法。介绍了气动—结构—强度跨学科迭代分析的基本过程，对气动分析及一种３维叶片—２维轮体有限元的耦合分析方法进行了讨论，给出了算例。
Proposed the overall impeller integrated conformal design method. The basic process of inter-disciplinary iterative aerodynamic-structural-strength iterative analysis is introduced. The aerodynamic analysis and the coupling analysis of a 3-dimensional blade with 2-dimensional wheel-body finite element are discussed. An example is given.
