Abstract:
To solve the problems of turbos，a multidisciplinary design optimization plat is pre— sented．At first，UG／Open Grip technique was adopted to parameterize the turbo．Then，the sample point distribution was obtained by the experimental design method，With the help of software Fluent and Ansys，the efficiency and stress of every sample points can be get．Therefore，the response surface model can be built up on these results and an optimization algorithm was adopted on the re— sponse surface model．At last，the optimization turbo was obtained．The results indicate that the effi— ciency of the optimization turbo Was increased by 5％．All results show the method is very important and available for improving the performance，reducing the loss，and others．
