夹层板在舰艇冲击防护中的研究进展

Advances in Study of Sandwich Plates for Ship Shock Mitigating

为了提高舰艇抗冲击能力,已发展了各种舰艇冲击防护方法。传统的冲击防护手段会使舰艇的重量大幅增加,影响舰艇总体性能。夹层板的出现给舰艇冲击防护提供了另外一条途径,成为近期国内外相关研究的热点。文中以舰艇冲击防护为背景,从夹层板的冲击变形模式、微惯量效应、应变率效应、几何非线性效应、流固耦合效应、以及均匀化和模拟试验方法等方面,回顾了近期国内外相关研究进展。

Various shock mitigating methods are provided to enhance naval ships＇ shock resistance. Conventional shock mitigating methods may increase the weight and reduce the performance of the ship. Sandwich plates serve as a new approach to mitigate ship shock harm, and have become one of the hottest research topics at home and abroad. With ship shock mitigating as the background, recent advances in the areas of sandwich shock deformation mode, micro inertia, geometrical nonlinearity, fluid-structure interaction, homogenization and shock simulating test are reviewed.
