临时开口船体结构强度数值分析

Numerical Analysis of Ship Structures with Cutting Hatch Openings

为了分析临时开口船体的结构强度,采用有限元方法建立典型舱段的数值模型,结合相关强度校核规范进行计算,结果表明开口的船体结构的抗弯、抗扭方面的安全性必须引起重视。通过分析得到开口参数对开口的结构强度的影响规律,对实际船体结构的临时开口具有重要的工程参考价值。

In order to analyze the strength of ship structures with cutting hatch openings, in this study, finite element models of ship structure are presented and strength analysis is performed based on correlate ship strength check criterions. The simulation results show that for ship structures with cutting hatch openings, it is necessalT to pay attention to the safety in respect of bend and torsion. The variations of stresses and distortions with cutting hatch sizes are also analyzed. This study provides an important reference for engineering application.
