摘要：
A multi-parameter optimization method for the natural frequencies of two-stage raft system is presented in this paper. The method can limit the natural frequencies in a relatively narrow band by quantitatively adjusting the natural frequencies of the system, which helps to avoid resonances and isolate vibration effectively. This method is of great significance in ship noise reduction engineering.
