【摘要】 在浮动冲击平台水下爆炸试验中，低频簧片仪的责片应变曲线展示了簧片对水下爆炸响应的全过程。在研究簧片应变曲线与水下爆炸作用外力对应关系时，发现了水下爆炸气泡膨胀产生的滞后流与舰船设备冲击振动响应的重要联系，并用丰富的理论和实验数据证实了“水下爆炸滞后流使舰船产生的（阶跃）位移是安装频率为数十赫兹的舰船设备冲击振动的主要能源”，而冲击波具有的能量对舰船设备冲击振动的贡献是微不足道的。更多还原

【Abstract】 in a series of tests for underwater explosion on a floating shock platform, we use the straincurves of a low-frequency reed gage to show the whole process of reed response to the underwaterexplosion. During analyzing the relation between strain curves and explosion forces, we find theclose links between afterflow, which is a product of bubble expanding, and shock and vibration response of ship equipment. Furthermore, basing on a lot of theoretical and experimental data, weverify the fact, "Afterflow of underwater explosion, which result in the stepped displacement of aship,is a main power source of shock and vibration for ship equipment at mounting frequency of tensHz,and the contribution of shock wave energy to the shock and vibration of ship equipment is negligible.更多还原
