舰船甲板结构的极限强度研究与结构优化
|
摘要
舰船甲板结构的强度具有非常重要的意义,是舰船安全运行的重要保障。为了提高舰船甲板在极端条件下(如导弹攻击、重物载荷等)的强度,本文首先对甲板结构强度理论进行了详细介绍,然后对舰船甲板进行了合理的简化和动力学模型建立,最后基于有限元分析软件Ansys平台进行了舰船甲板的建模、网格划分、极限强度下的载荷仿真等内容,对提高舰船甲板的安全性能有重要的意义。
The strength of ship deck structure is of great significance and an important guarantee for the safe operation of ships. In order to improve the strength of ship deck under extreme conditions(such as missile attack, heavy load, etc.), this paper firstly introduces the theory of deck structural strength in detail, then simplifies and establishes a reasonable dynamic model of ship deck. Finally, based on the finite element analysis software ANYS platform, ship deck modeling, meshing and load under ultimate strength are carried out. The simulation and other contents are of great significance to improve the safety performance of the ship deck.
