提出了一种基于条带理论来预测规则头波中耦合升沉/纵摇运动和垂直载荷的非线性响应的方法。非线性来自船体湿润部分的波浪压力的积分，以及包括耀斑、底部撞击和甲板湿度的影响。该公式基于船长量级的长波。在时域中求解方程，给出结果并与线性理论和模型测试获得的结果进行比较。一般来说，模拟和模型测试结果之间具有良好的一致性。
A method to predict non-linear response of coupled heave/pitch motions and vertical loads in regular, head waves based on strip theory is presented. The non-linearities come from integration of the wave pressure over the wetted part of the hull, and by including effects from flare, bottom slamming and deck wetness. The formulation is based on long waves, of shiplength order. The equations are solved in the time domain, and results are presented and compared with those obtained from linear theory and model tests. Generally good agreement is achieved between the simulations and the model test results.
