基于SWATH船型回转横倾角的舵设计

Rudder Design Based on Heel Angle of SWATH’s Turning Motion

摘要:

以小水线面双体船满舵回转时的稳定横倾角和舵的水动力性能(侧向力)为研究对象，以 CFD 计算为基础，开展不同舵面积比对回转横倾角和舵机功率的影响分析，分别评估了舵面积比为 3.0%和 4.0%共 2 种工况，并结合舵设计的一般规范、方法进行分析，可为 SWATH 船型舵面积的设计提供参考和依据。

Abstract:

In this paper，the stable heel angle and the hydrodynamic performance(rudder side force)of SWATH during full rudder rotation are the research objects. Based on CFD calculations，the influence analysis of different rudder area ratios on the rotary heel angle and the power of the steering gear is carried out. The two working conditions with rudder area ratio of 3.0% and 4.0% are evaluated separately，and anauzed in combination with the general rules and methods of rudder design，which can provide reference and basis for the design of SWATH rudder area.
