水下非接触爆炸作用下舱段模型的动态响应

Dynamical response measurement of a cabin model subjected to noncontact underwater explosion

对舱段缩比模型遭受水下爆炸冲击载荷时的动态响应进行了测量与分析.模型是参照水面舰船的典型舱段而设计的.用于评估普通船用钢材料模型的冲击响应。试验工况为远场非接触爆炸,介绍了药包/模型的几何特性.以及用装在舱室内、甲板处和龙骨上的加速度计来测量舱段模型的冲击运动。

Dynamical responses of a cabin model under far-field underwater explosion load were experimentally measured and theortically analyzed. The scale model was designed by referring to a representive cabin of naval ships and was used to assess the shock response of common hull steel models. The shock motions of the model were recorded by the accelerometers mounted on the model bulkheads and deck plate. The geometry characteristics of the charge and model and the disposals of the accelerometers were presented. Researched results are helpful to the future model experiments.
