| 摘 要： | 提出了同时考虑流固耦合和材料应变率强化效应时,加筋板结构在水下爆炸冲击波作用下动态响应的相似条件.在此基础上,提出了该问题的近似相似方法.该方法通过在模型和原型之间建立一个修正模型,达到利用修正模型的冲击响应近似预报原型响应的目的.最后提出了利用缩比模型试验预报原型冲击塑性变形的模型化试验方法.文中结论可用于指导利用模型试验预报船体局部板架在水下爆炸冲击波作用下动态响应.

| Abstract: | The dynamic response scaling law between a model and aprototype stiffened plate subjected to underwater explosion blast is presented when both liquid-solid coupling and strain rate effect is considered.By this method,a correct model is presented between model and prototype stiffened plate in order to predict the permanent displacement of prototype stiffened plate.Finally,a scaling experiment method is brought forward to predict dynamic reponse of ship local structure subjected to underwater explosion blast. |
