中文摘要:
      舰载设备抗冲击能力对舰艇生命力十分重要,实验测量因消耗大且危险性高不能大量开展,数值仿真技术的发展为舰载设备考核提供了新的手段。通过基于声固耦合法的有限元分析技术对某小型浮动冲击平台(FSP)进行数值仿真实验,并与实爆实验结果对比,验证了缓冲平台基座处冲击加速度峰值和冲击谱仿真计算的正确性。结果表明,该方法可为舰载设备提供准确的冲击环境输入,可对该型FSP进行准确的冲击环境预报,研究成果可推广应用到中大型FSP。
英文摘要:
      The anti shock ability of naval ship equipment is very important for ship vitality. For the reasons of cost and safety, the real test measurement cannot be processed frequently. The technology of numerical simulation provides a new method for ship equipment evaluation. The finite element analysis technology based on acoustic structure interaction method was used to simulate the shock response of a small floating shock platform(FSP) numerically. Then, the real time explosion test validated the peak acceleration and shock response spectrum compared to the simulated result. The results showed that numerical simulation can provide the exact input for ship equipments and predict the shock environment of the FSP accurately. The method can be extended to medium and large FSP.
