爆炸载荷作用下的船用吸能防护结构

The Energy Absorbing Protection Structure of Ship under the Explosion Loading

重要舰船或舰船的重要部位采用吸能防护结构的必要性已逐渐被人们所认识和接受。防护结构性能好坏的主要指标是培构总能量吸收量和比耗能,本文分析了3种船用吸能防护结构在爆炸最荷作用下的破坏形式,给出了相应的能量吸收估算公式及计算蛄果,比较了等重量下不同防护结构的吸能量和比耗能,从而为船用吸能防护结构用于抗爆炸设计提供了依据和方法。

The necessity to use the energy absoring protection structure in the important ships or at the important parts of the ship has been recognized and accepted. The total energy absorbed and the energy absorbance of the structure are important performance index for the energy absorbing protection structure. In this paper, the destruction models of three different energy absorbing protection structures of ships are studied and the estimating formulas of the energy absorbed are given correspondingly. The energy absorbed and the energy absorbance of the three different protection structures are compared in the same weight. So that, the basis and the method to make the energy absorbing protection structure used to the explosion protection design of ship are obtained.
