以提高破损后抗风能力为目标的主分舱优化设计是提高军用舰船生存能力的一条好途径。从水密分舱入手，提出了以提高破损后抗风能力(额定风速)为目标的横向水密舱壁位置优化设计方法。考虑最严重的三舱损伤情况，以横向水密舱壁位置为设计变量，建立了以损伤后“平均抗风量”为目标函数的优化模型，并利用遗传算法进行寻优。通过某护卫舰的算例验证了该方法的有效性。
A good way of enhancing the survivability of military ships is main hull subdivision optimization design aiming to improve anti-wind capacity after damage. Begin with the watertight subdivision, this paper puts forward a method of the transverse watertight bulkhead position optimization design for improving anti-wind capacity (rated wind velocity) after damage. Taking the most serious three-compartment damage situation into consideration, transverse watertight bulkhead positions serving as design variable, the optimization model with objective function of “Average Anti-wind Capacity” after damage is established, and genetic algorithm is used to get the optimal solution. The effectiveness of the method is confirmed by a calculation example of one frigate.
