力学与声学超材料在船舶工程中的应用研究综述北大核心CSCD

海洋环境的复杂性以及兵器攻击中强非线性载荷的作用,使得采用常规材料制造的舰船结构难以满足安全性、隐身性、轻量化和舒适性等综合设计指标要求,而超材料凭借其性能的人工可设计性和性能超颖性,成为解决上述工程需求的有效途径之一。总结近10年来超材料在船舶工程中的理论及应用研究现状,围绕船舶抗爆抗冲击、轻量化、承载和减振降噪等几个方面,重点梳理力学超材料和声学超材料的设计方法与应用研究进展。指出船用超材料的大尺度、高效、低成本制造技术是未来船用超材料应用中亟待突破的方向与瓶颈,船用超材料的高承载性、宽频段带隙设计和低频段带隙设计已成为具有潜力的研究热点。

Review on the applied research of mechanical and acoustic metamaterials in ship engineering

The complexity of the marine environment and the strong nonlinear loads of weapon attacks make it difficult for ship structures made of conventional materials to meet the comprehensive design requirements for safety, stealth, lightweight, comfortability, etc., while the artificial designability and performance hypersynthesis of metamaterials have made them an effective way to solve the above engineering requirements. Starting with applied research, this paper summarizes the theoretical and application research status of metamaterials in ship engineering over the past ten years, focusing on such aspects of mechanical metamaterials and acoustic metamaterials (AMMs) as their lightweight, vibration and noise reduction, and anti-blast and anti-shock properties, as well as research progress on design methods and applications. The large-scale, high-efficiency and low-cost manufacturing technology of marine metamaterials is the direction to follow and the bottleneck to break through in the future engineering application of marine metamaterials. The high load-carrying capacity and wide-band/low-frequency bandgap design of marine metamaterials have become potential research hotspots. © 2023 Editorial Department of Chinese Journal of Ship Research.
