波浪对穿浪双体船摇荡运动的影响

穿浪双体船作为一种新船型,逐渐在近海高速客运领域中发挥重要作用。研究穿浪双体船在不同海况条件下的摇荡运动规律具有重要意义。本文采用修正切片法计算某穿浪双体船的纵摇、垂荡以及横摇运动的幅值响应函数,并采用谱分析的方法统计计算其在不同海况条件下的摇荡运动规律,通过零航速时计算结果与试验结果的比较,验证了本文计算方法的正确性。最后,对本文计算对象在不同海况条件下的摇荡运动规律进行了分析。

Research on wave-piercing catamaran features of swaying motions in the waves

Wave-piercing catamaran form as a new,high-speed passenger transport in coastal areas gradually play an important role.Research on wave-piercing catamaran’s swaying motions in different sea conditions has great significance.The research use STF method to calculate piercing catamaran pitch,heave and roll motion of the amplitude response function,and use spectral analysis to calculate sway movement in different sea conditions.On the basis of comparing zero speed results,verifies the correctness of this method.Finally,analyze the object’s sway movement law in different sea conditions.
