摘要
在舰船破损进水过程的横摇运动时域模型的基础上,求解得到横摇运动的时域曲线;对此时域曲线通过特征提取得到其破损模式的识别属性;通过案例推理技术建立舰船破损模式识别算法。该识别算法的实现可为舰船抗沉决策提供准确的破损信息,有利于舰船的防沉抗沉。
The heeling motion time domain model of the damaged ship is the basic theory, and the heeling time domain curve is obtained through numerical simulation. Then the curve attributes are extracted as recognition characters of the damaged ship. Lastly, ship damaged mode recognition arithmetic is set up, which is useful for providing correct ship damage information to improve insubmersibility.
