摘要(Abstract):

针对动态设计分析方法(DDAM)评估舰艇设备抗冲击性能与水下非接触爆炸条件联系不够紧密的不足,利用水面舰艇水下非接触爆炸数值仿真,得到不同工况下水面舰艇甲板设备垂向响应及冲击反应谱;结合联邦德国军舰建造规范BV043/85规定的正负三角波作为加载波形,加载到舰船甲板安装设备等效动力模型上,计算得到不同安装质量设备的甲板基础冲击反应谱,作为甲板安装设备抗冲击设计谱值。得到的抗冲击设计谱规律正确,数值合理。
Owing to the Dynamic Design Analysis Method(DDAM) being lack of close correlation with the condition of non-contact underwater explosion,the shipboard shock environment of non-contact underwater explosion was adopted for numerical simulation with ABAQUS program to obtain the shock response in vertical direction and its shock spectrum of the different mass of shipboard equipments under different working conditions.The plus-minus triangular loading wave proposed by the German Criterion BV043/85 was used as carrier wave to load on equivalent dynamic model of deck equipment for calculating out the basic shock waves which were taken as the design values of spectrum.The obtained design spectrum had the correct law and suggested rational value.
