摘　　要：对于浮动冲击平台在水下非接触爆炸作用下的冲击响应进行了测量、分析.采用NI公司的采集机及PCB传感器对平台结构的冲击响应(速度、加速度、位移、自由场压力、应力)进行测试,得到不同爆距、平台结构的数值,分析了药量、爆距、平台结构(等爆炸因子)对冲击响应的影响,结果表明:爆距对冲击响应的影响呈非线性变化,结构对冲击响应值影响很大.The shock response of the floating shock platform under the un-contacted explosion act in the water has been measured and analyzed.Using NI equipment and PCB sensor,the shock response of the platform has been tested,such as velocity,acceleration,displacement,free field press and construct stress.The influence of dynamite quantity,explosion distance and platform structure to shock response has been investigated by analyzing measure results.The results show that the influence of explosion distance to shock response represents nonlinear trend and platform represents strong effect.
