| 摘 要： | 在水面舰艇声隐身论证阶段,由于设计输入不足,难以对振动噪声情况进行数值预报。文章提出了一种表征船体不同部位机械振源影响情况的结构影响因子方法,进行了典型水面舰艇主要振源、结构部位对局部自噪声的影响分析,建立了主要振源工况、结构部位与局部自噪声的量化关系,可为水面舰艇声隐身论证提供量化支撑。

| Abstract: | The numerical forecasting of vibration and noise of surface ship is hardly operated for lack of data in the stage ofdemonstration. A forecasting method by structural influence factors of vibration and noise of surface ship was presented inthis paper. The quantitative relationships between working conditions, position structure and self noise at certain positionof a typical surface ship were established, and could support the quantitative demonstration for the acoustic stealth of sur.face ships. |
