The invention relates to a method for calculating a horizontal attitude swing period of a naval vessel, the swing period selects a peak period, and the method comprises the following steps: step 1, determining a horizontal attitude swing period boundary value oriented to the actual demand of a user; step 2, performing curve fitting and extreme point extraction on the effective horizontal attitude angle numbers, wherein the horizontal attitude angle numbers comprise ship dynamic pitching angle data and ship dynamic rolling angle data; 3, carrying out quantitative calculation on the horizontal attitude swing period of the naval vessel; and 4, quantitatively displaying the horizontal attitude swing period of the naval vessel according to the actual requirements of the user. According to the calculation method, the recent-moment swinging period and the historical swinging period of the naval vessel can be provided for a user for online calculation.
本发明涉及一种舰艇水平姿态摇摆周期的计算方法,摇摆周期选择峰值周期,包括如下步骤:步骤1、面向用户实际需求的水平姿态摇摆周期边界值确定;步骤2、对有效的水平姿态角数分别据进行曲线拟合和提取极值点,其中水平姿态角数包括舰艇动态纵摇角数据和舰艇动态横摇角;步骤3、舰艇水平姿态摇摆周期量化计算;步骤4、面向用户实际需求的舰艇水平姿态摇摆周期定量显示。本计算方法能够为用户提供在线计算的舰艇最近时刻摇摆周期及历时摇摆周期。
