基于ANSYS的舰船武器装备基准变化分析方法

舰船武器装备基准在外界环境作用下产生变化，从而影响武器系统的打击精度。应用ANSYS平台建立舰船有限元模型，利用三维波浪载荷的计算方法模拟航行条件下的波浪力，研究了舰船甲板面武器装备基准在两种极限海况下的变化情况，发现针对此类舰船横摇使武器装备基准产生较大的变化，并且靠近尾部和两舷位置处装备的基准变化较为显著。仿真结果表明：当舰船在风浪中航行使用武器系统时，应尽量采取顶浪航行，减少舰船横摇对武器系统基准的影响。

Vessel Weapon System Reference Deviation Analysis Based on ANSYS

Vessel weapon system reference deviation caused by external condition affects attack accuracy. The finite element model was constructed though ANSYS environment. 3D wave loads calculation method was used to simulate the wave force in sailing condition. Vessel deck weapon system reference difference along with double limiting sea condition was researched. Vessel deck weapon system reference was affected by vessel roll significantly and reference of weapon nearby the sten and board was variable evidently. The results indicate that the vessel course could be against wave while weapon system was in used, which weapon system reference could be less effected by vessel roll.
