摘要
采用线性屈曲与非线性屈曲中的弧长法对载人潜水器耐压球壳的稳定性进行分析,分别采用CCS、GL两种规范进行校核与比较,改进观察窗座的结构形式;并针对多开孔球壳模型,采用弧长法分析其临界失稳压力,以保障人员及设备的正常工作与运转。
This paper analyzes the stability of spherical pressure hull of manned submersible by arc-length method in linear and non-linear buckling. It improves the structural form of observation windows after the check and comparison of results obtained by CCS and GL regulations. It also analyzes its critical buckling pressure of spherical hull with multi-holes by arc-length method ,which ensures that personnel works normally and equipment runs orderly.
