Abstract

The multi-objective optimization design for complicated reinforced cylinder structures was discussed by combining the ISIGHT multidisciplinary optimization design framework. Firstly, the mathematical model of acoustic radiation optimization of cylinder structures was established for sound and vibration analysis of simulation objects, thus determining the optimal design parameters. Secondly, software frameworks were integrated and the multi-objective optimization process was designed based on the ISIGHT platform. Finally, iterative computations were carried out by the optimization platform. This is the end of optimization operation. Results demonstrated that acoustic characteristics of the reinforced cylinder shell structures are improved to some extent after size optimization. The optimization is fruitful.
