| 摘 要： | 舰船甲板作为甲板安装设备的基础,甲板动力模型对设备承受的冲击有很大影响。利用甲板的模态信息,合理的假设条件,提出甲板单自由度等效动力模型和两自由度等效动力模型。应用德国舰船抗冲击规范BV043/85规定的正负三角波载荷,对等效模型和有限元真实甲板模型抗冲击分析,比较了有限元模型和单自由度、两自由度等效动力模型的位移、速度、加速度以及冲击反应谱。结果表明提出的等效动力模型是正确的。两自由度等效动力模型较之单自由度等效动力模型,能更加真实反映甲板高频特性。 |

| Abstract: | Shipboard has a great influence on equipment while equipment suffer a shock.Through modal analysis and reasonable hypothesis,the single degree of freedom systems and double degree of freedom systems were attained.The shock analysis of FEM model and dynamics model was carried out,and the results of displacement response and velocity response and accelerate response and shock response spectrum were contrasted.The results show that the SDF and the double degree of freedom system were feasible.The double degree... |
