浮心纵向位置对某破冰调查船兴波阻力的影响
|
Abstract:
本文采用基于母型船的方法对某破冰调查船进行半参数化建模，并利用FRIENDSHIP-Framework系统中的Lackenby变换方法，对该船前部进行参数化变形，以排水量为限制条件，探讨浮心纵向位置与兴波阻力之间的变化规律。较为直观地给出了该船兴波阻力系数相对浮心纵向位置的变化规律曲线，发现存在一个最优纵向浮心位置，使得兴波阻力最小。
A semi-parameterized modeling method is used based on parent ship of an Icebreaker. The method of Lackenby shift in FRIENDSHIP-Framework system is applied to reform the forward part of the ship. Keep the displacement of the ship unchanged. The wave resistance is discussed versus the longitudinal position of the center of buoyancy. A figure of the variation of the wave resistance coefficient versus the position of the buoyancy is displayed. The optimal longitudinal position of the center of buoyancy is investigated to make the wave resistance lowest.
