摘要
通过有限元分析,对某大型舰载设备天线舱在摇摆工作状态下进行了力学特性分析和优化。其中,根据工字梁结构屈曲分析理论,对其在不同动态载荷工况下底层结构的工字钢腹板稳定性进行研究,并对舱底层结构在不同方向风载的结构应力分布进行了仿真分析,提出了使用指导意见,其研究成果可为天线舱进一步优化提供基础。
In the present paper, the mechanical behavior of antenna-cabin on capital ship under rolling and pitching situations has been investigated by means of finite element analysis. The stability of underlying I-beams under different dynamic loads has been discussed based on the buckling theory of I-beams. Simulation analysis of underlying structural stress with wind loads in various directions has been done. The results can be used in the further optimization design and applications of antenna-cabin.
