摘要: This paper presents an anti-erosion design approach of multidisciplinary optimization (MDO) for turbomachinery to improve the erosion resistance blades, and its application industrial mixed flow fan is given. The method based on a concept in aerodynamic stage by modifying geometry turbomachinery. MDO replaces traditional time consuming through automatic analyses performance, stress distribution characteristics, controlled strategy. In approach, multi-objective algorithm non-dominated sorting genetic algorithm-II combined with radial basis function meta-model used find compromise between conflicting demands high-efficiency low average rate constraints pressure ratio safety factor blade; finite element analyze static mechanical re...
