Multi-Objective Optimization Design Method for Whole-Aeroengine Coupling Vibration

چکیده
With the increasing thrust-to-weight ratio of modern aeroengines and widespread adoption thin-walled casing, impact coupling vibration effect between rotor stator on critical speed, rotor–stator mode shape coordination, response characteristics whole engine have become increasingly prominent. However, vibrational design whole-engine has thus far relied human experience, revealing a need for study its intelligent optimization. In this study, to quantitatively analyze engine, three evaluation indexes were defined, which risk coefficients strain energy, cross-section rubbing. Using these as optimization targets, multi-objective method aeroengine support stiffness was proposed. The turbofan with large bypass performed. results showed that index machine can be reduced different degrees is optimized.

The coupling of performance functions due to common design variables and uncertainties in an engineering design process will result in difficulties in optimization design problems, such as poor collaboration among design objectives and poor resolution of design conflicts. To handle these problems, a fuzzy interactive multi-objective optimization model is developed based on Pareto solutions, whe...

متن کاملTowards Multi-Objective Optimization for UI Design
In recent years computational optimization has been applied to the problem of finding good designs for user interfaces with huge design spaces. There, designers are struggling to integrate many different objectives into the design process, such as ergonomics, learnability or performance. However, most computationally designed interfaces are optimized with respect to only one objective. In this ...
