摘　　要：为分析武器爆炸地震动下橡胶隔震对贮液结构动力响应的影响,利用爆炸冲击震动模拟平台对隔震与非隔震的箱体贮液结构进行试验研究,获得贮液、无液时结构的加速度和应变参量,分析了橡胶隔震措施、贮液情况对结构加速度和应变响应的影响。利用数值模拟研究了隔震与非隔震贮液结构的冲击震动响应,与试验结果进行了对比。结果表明:增加橡胶隔震层能够有效降低结构振动的加速度和应变峰值,使加速度峰值沿结构高度的放大系数明显降低,结构贮液时增加隔震层的减震效果更显著。In order to analyze the influence of rubber isolation on the dynamic response of liquid storage structure under the ground motion of weapon explosion, this paper carries out an experimental research on the liquid storage structure of isolated and non-isolated boxes by using the explosion shock vibration simulation platform to obtain acceleration and strain parameters of the structure with or without liquid.Then, the effects of rubber isolation measures and liquid storage on structural acceleration and strain response are analyzed.Finally, numerical simulation is used to study the shock and vibration response of isolated and non-isolated liquid storage structures, which is compared with experimental results. The results show that adding the rubber isolation layer can effectively reduce the acceleration and strain peak value of the structure vibration and significantly reduce the amplification coefficient of the peak acceleration value along the structure height. The damping effect of adding more isolation layers is more significant when the structure stores liquid.
