摘要
以数学模型求解舰船风中运动中的风力系数是一种新方法,该方法无需风洞试验数据,直接利用舰船实测风压差表,借助别尔舍茨方法,可求得舰船在Y方向上的风力系数CWY及舰船风力矩系数CWN。经算例验证,能满足海上实践的需求。
This article gives a new method for wind coefficient on ship. The new method do not needs data of wind tunnel. The new method can calculate the wind coefficient on ship by using the leeway angle table on ships and by the method of Пepщчя. Through the verifying examples, we can conclude that the method fit well of the practice.
