舰艇结构在水下爆炸冲击作用下损伤响应的相似问题研究框架及其工程应用

Analysis of scaling method of warship subjected to undex

通过对加筋板结构在水下爆炸冲击波作用下相似问题的研究方法进行扩展,指出舰艇结构在水下爆炸冲击作用下损伤响应相似问题的研究应分为三步,即准确相似条件研究、近似相似方法研究和模型实验方法研究。在此基础上,提出了相似问题研究的工程运用方向:舰艇结构损伤响应的模型试验预报和舰艇结构损伤图谱。该问题若按所提出的研究框架展开,最终可建立舰艇结构在水下爆炸作用下损伤响应的相似预报体系和用于舰艇结构抗爆抗冲击设计的结构损伤图谱。

The frame was presented for the scaling research on the dynamic response of warship structure subjected to underwater explosion（undex）.The research of this problem was extended from the result of scaling research on the dynamic response of stiffened plate subjected to undex.The research was divided into three steps： First,the exact similar research conditions;second,approximate similar research method,and third,the model experiment method.Based on these,two application directions of scaling research were presented,which were the prediction of the dynamic response of warship structure subjected to undex by model experiment and damage atlas of warship structure.
