摘　　要：采用有限元法研究了承受横向压力时,耐压舱壁长圆门区域结构的变形。提出了一种分析长圆门围栏与舱盖接触端面变形的方法。通过参数化建模,进行多参数的离散变量分析,揭示围栏变形的规律。提出控制接触面变形的设计要求,以保证新型舱门的密封性。This paper analyses the deformation of submarine bulkhead oblong-hatch in the case of transverse pressure by using FEM. An approach is developed to calculate the displacement of the interface between the hatch plate and its strengthening wall. Then, based on parameterized modeling, an analyse through discrete multiparameter regulation is carried out, and the deformation mode of strengthening wall is revealed. As a result, this paper figures out the demands of structural design which intend for constraining the displacement of the interface, and therefore, the capability of water proof of the hatch can be ensured.
