针对一般约束和将舷外水简化为附连水质量及水弹簧约束的三舱段模型,分别计算舱内和空中爆炸载荷作用下的舱段结构响应,对其主要响应特征的塑性变形进行比较分析。分析结果表明:在研究舱内爆炸问题时,舷外水对结构抗爆响应的影响较小,可以忽略;而在研究空中爆炸问题时,舷外水对结构抗爆响应的影响较大,必须计及。
Regarding the common three-cabin model and the three-cabin model with added mass and water spring as the research object, this paper calculated the structural response and plastic deformation of the target cabin subjected to inner explosion and external explosion, respectively, and made comparisons. The result indicated that the effect of surrounding water on structural response of cabins subjected to inner explosion was relatively smaller and could be neglected while that subjected to external explosion was relatively bigger and should be taken into consideration.
