Abstract

The study on MDO(multidisciplinary design optimization) technology is applied on compressor design and a multidisciplinary feasible system is set up to automatically optimize the design of centrifugal compressor. In this system, non-uniform rational B-spline is used to define radial blade profile and quintic polynomial with continuous three order derivatives is used to define diffuser blade profile. The transfer of load and deformation are finished by direct interpolation and the mesh regeneration methods. Based on parametric model design and coupling analysis methods, a centrifugal compressor is used to validate the feasibility of the optimization design system, the case study show that, optimization efforts could improve obviously the performance of centrifugal compressor. The calculation proves that the system is feasible, which can be applied on other multidisciplinary design system.
