| 摘 要： | 在用船舶降噪工程受总体约束强、声学异常多等因素影响,传统新船建造的声学设计方法不能被直接应用。为此,提出了在用船舶降噪工程技术集成优化方法。根据需求设计顶层降噪指标,并通过四项标准进行检验;基于改装前测试数据和降噪技术储备情况,制定初步降噪技术集成方案;通过声学评估迭代,形成优化的指标分配体系和最终的降噪技术集成方案。模型试验验证结果表明,该方法能够有效实现在用船舶降噪工程的技术优化集成。

| Abstract: | For the noise control of the in-service ships, due to the rigid limit of the general conditions and the acoustical abnormity, the traditional acoustical design method of the new ships cannot be used directly. For the noise control of the in-service ships, the optimized integrating method of the techniques is proposed. Firstly, based on the tactical requirement, design the top noise-control targets, and validate the targets with four criteria. Then, combining the noise data of the refit test and the existing techniques, establish the primary composition project of the noise-control techniques. At last, with the acoustical evaluation and optimizing, obtain the optimized distributive system of the targets and the final composition project of the noise-control techniques. The method is validated with a model experiment. The results show that the method can realize the optimized composition of the noise-control techniques, in the refit of the in-service ships. |
