英文摘要：

Complex cylindrical structure is the main lype of ship structure. It is much valuable to present an acoustic optimization method for complex cylindrical structures for realizing the idea of design driven by analysis in ship structure acoustic design. The parametric model library of complex cylindrical structures is designed and founded with the implicit parametric method. Then an acoustic optimization method based on the parametric models for complex cylindrical structures is introduced, and methods for transferring datum, starting software and controlling variables are given. Numerical results show that the present method is reasonable and can satisfy the optimization design requirements of ship complex cylindrical structures.
