摘　　要：某舰载核探测设备在爆破冲击作用下,易造成核心探测器件的破坏和失效,由此设计了减振腔结构以实现缓冲和减振。采用电动振动测试系统产生的半正弦冲击波,对减振腔进行了多组冲击载荷试验,获得了减振腔在输入系列冲击振动载荷下系统输入-输出特性的数据,通过分析计算得到了系统的减振比。结果表明,减振腔系统具有良好的抗冲隔振性能。Under the strike of the blast,the certain warship nucleus detector is easy to destroy and its core apparatus are in invalidation. So the structure of the shock absorber cavity is designed to achieve cushion and reduce shock. The half-sine shock wave made by electromotion vibration testing system is applied to the shock absorber cavity ,and the test results of the its input-output characteristic data is gathered while different groups of loads is input. By analyzing and calculating of the data, we can receive its reducing shock ratio. The test results show that the system possess favourable performances of antishock and isolation vibration.
