Multidisciplinary Design Optimization of Turbine Disks Based On ANSYS Workbench Platforms
The design of aero engine turbine disks,which are working under high thermal and centrifugal loads,is an interactive and multidisciplinary process that includes several disciplines,such as aerodynamics,structural analysis,mechanical design,and heat transfer etc.Considering the actual aero-thermal-structure coupled environment,the main challenge for the designers is to produce an optimum design that satisfies all the design criteria such as weight,life,efficiency and reliability.Especially,problems of overweight and maximum localized stress have been always encountered for designers in the preliminary design phase.Therefore,there exist contradictions for the design parameters from different disciplines,and then multidisciplinary design optimization method could be a very valuable and efficient strategy to solve the problem.In this paper,based on the platforms of ANSYS workbench software,the aero-thermal-structure coupled analysis of a high pressure turbine disk had been conducted.Then,the parameters of width and height of the disk bore were selected as the design variables,and multidisciplinary design optimization of turbine disk had been done.As a result,with the constraints on strength criteria,the objective function of disk weight had been decreased by 6 percents which achieved the expected goal and significantly reduced the design and research time.
