摘要

摘要: 针对航空发动机涡轮盘结构优化设计，在等热负荷及等冷气耗量前提下，采用热边界载荷控制构建轮盘上有利的温度分布，以ISIGHT软件为基础搭建的集建模-CFD分析-FE（有限元）分析-优化设计在同一流程下的多学科优化设计平台为工具，研究热边界载荷优化在涡轮盘优化设计中的应用效果.结果表明：热边界载荷的优化可以实现质量减轻和应力水平同时下降的目的，下降水平决定于热边界载荷分配系数，当热边界载荷分配系数取0.1和0.2时，盘心最大等效应力下降值分别为5.93%和12.01%，质量下降值分别为1.25%和2.24%.

Abstract: For the optimization design of aeroengine turbine disk structure, the reasonable temperature and stress distribution was obtained by changing the thermal boundary loading coefficients of rim and hub under the constant heating and cooling condition. An optimization design process including modeling,CFD analysis, FE(finite element analysis) was developed based on ISIGHT softwave which is used to solve fluid-heat-structure coupling problems and the effect of optimization design of turbine disk structure imposed on thermal boundary loading was explored. Result shows that the optimization result varies from the different thermal boundary loading coefficients.The maximum equivalent stress of disk hub decreases 5.93% and 12.01% respectively, the mass of disk decreases 1.25% and 2.24% respectively when the thermal boundary loading coefficients of 0.1 and 0.2.
