新型大潜深平台多耐压体连接结构设计

采用规范和有限元方法,对560m静压作用和坐墩工况下的某虚拟大潜深载人平台耐压壳与轻外壳之间的连接结构进行了设计和力学分析。在静水压力工况下,先根据总体布置提出并排的三耐压圆柱壳外部连接结构舱段方案;然后通过有限元方法,研究各方案的结构受力规律,通过受力分布特性对结构逐步修改;最后给出整艇结构方案和连接结构的受力特性以及连接结构对三耐压壳体的受力影响规律。通过计算分析及对比,得出了此艇结构在4种坐墩工况下的受力规律。

Design on a new-type large diving depth platform multi poressure shells bonded structure

Adopting rule and finite element method,the paper has designed and analyzed the bonded structure between poressure shell and light shell ofa virtuallarge diving depth manned platform under560m hydrostatic pressure effect and lying on the keel block.Under hydrostatic pressure,it put forward the cabinsegment project ofthree poressure column shell exteriorbondedstructure side byside accordingto general arrangement,then through finite element method,researching the structure under stress rules ofprojects and mo...
