概要

• 論文の詳細を見る

• This paper introduces an optimum design system developed for turbo machinery rotors, and discusses several application results. The sequential linear programming method is used in the optimizing process, and unsteady state thermal analyses of variable thickness wheels are performed using the numerical analysis method of multi-ring model. Centrifugal and thermal stress analyses of these wheels are performed using Donath's method with same multi-ring model. These systems' validity is confirmed by application to uniform strength rotating disk problems and by comparison with analytical results. This optimum design program is then applied to the design of axial flow compressor wheels.
