| 摘 要： | 改进船体结构耐撞性是开展船舶碰撞研究的一个主要目的.结构耐撞性设计,就是在碰撞研究的基础上,对传统的舷侧结构进行优化设计,或者设计一些具有特殊吸能元件的新型船体结构形式,来改善船舶的结构耐撞性能.目前,船舶耐撞性的研究主要集中于双层舷侧结构,单壳舷侧结构的耐撞性研究开展得较少.IFP(Improved Frame Panel)是一种先进的舷侧骨架结构,它具有良好的吸能特性和结构强度,是一种理想的能量吸收单元.本文基于IFP构建了一种新式单壳舷侧耐撞结构,并将之应用于某型护卫舰.通过仿真计算和比较研究,证明IFP可以显著提高舰船的侧向抗撞能力,是一种先进的耐撞设计思想.

| Abstract: | Structural crashworthy design means,based on ship collision study,optimizing its traditional side structure or designing some new crashworthy type with special energy-absorption unit to improve ship's crashworthiness. IFP (Improved Frame Panel), a kind of advanced frame panel side structure, has a good capacity of energy absorption and structural strength and is an ideal energy absorption unit.A new crashworty type of single hull structure against collision based on IFP is proposed in this paper.Applied to a frigate's side, IFP is proved to be an advanced crashworthy design that can remarkably improve the side structure's ability against collision by numerical simulation. |
