以航空发动机整体压气机转子优化设计分析为工程背景,建立整体压气机转子的优化模型,选择重量最轻为目标函数,进行轴对称热弹塑性有限元分析,采用设计尺寸、局部应力、局部低循环疲劳寿命、轮盘破裂转速等约束函数,同时还在形状描述方式、自动分网、灵敏度分析、后处理接口等方面作了大量研究工作,在此基础上研制了整体压气机转子优化设计程序,并应用到实际压气机转子和涡轮盘优化设计,在满足强度和寿命要求的同时,转子重量有较大幅度下降
Taking the optimization design and analysis of the whole compressor rotor of aeroengine as the engineering background, an optimization model of the whole compressor rotor is established, and the lightest weight is selected as the objective function to carry out the axial symmetric thermo-elasto-plastic finite element analysis. The design dimension, local stress, Cyclic fatigue life, and wheel rupture speed. At the same time, a great deal of research work has been done on shape description, automatic network division, sensitivity analysis and post-processing interface. Based on this, the overall compressor rotor optimization design program , And applied to the actual design of the compressor rotor and turbine disk optimization, while meeting the strength and life requirements, while the rotor weight is more substantial decline
