摘　　要：舰船武器装备基准在外界因素作用下产生变化,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舰船所受载荷,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。仿真结果表明:针对所选取的某型舰船主体结构而言,舰船横摇使武器装备基准产生较大的变化,并且靠近船体尾部和两舷位置处装备的基准变化较为显著,所以该型舰船在执行作战任务中,应尽量采取顶浪航行,减小舰船横摇对武器装备基准的影响。Vessel weapon system baseline deviation caused by external condition affects attack accuracy. The finite element model is constructed by ANSYS. 3D wave loads calculation method is used to simulate the wave force in sailing condition. Vessel weapon system baseline deviation in the case of two limit sea conditions is researched. The simulation result indicates that vessel weapon system baseline deviation of certain vessel structure of this text is remarkable in the rolling condition and the weapon baseline near stern and broadside has a tremendous influence. Therefore this certain vessel should be sailing a- gainst wave while it carries out combat duty in order to decrease the influence of rolling.
