摘　　要：针对排水型舰船尾部线型特征,提出船体尾部呆木线型设计的数学函数,定义了呆木线型的特征量,并设计了系列呆木线型;运用有效展舷比概念扩充了船体水动力经验公式,得到呆木线型对船体水动力影响的估算方法;采用"分离型"操纵性数学模型预报了系列呆木对舰船操纵性的影响,得到呆木面积与航向稳定性提高成正比等结论。According to the feature of the displacement ship＇s stern form,the mathematical equation of the dead wood was proposed,and the characteristics were defined,a series of dead wood forms were designed.Combining the Kijima＇s method of calculating hydrodynamic forces with the effective aspect ratio,the effect of the dead wood on hydrodynamic forces of the hull was explored,and an evaluation method for the effect was provided.By using the separate maneuvering prediction method,the dead wood＇s effect on the maneuverability was calculated.The results show that the adding of the straight-line stability is proportional to the area of the dead wood.
