海洋母子风帆船的稳性研究

在对母子风帆船以及一般风帆船分析和比较的基础上,研究了母子风帆船及其节能技术和稳性.通过合理配置母船与子船的适当流体间距,采用对船舶最大横截面点仿真的分析方法,在母船基础上两侧各增加一子船,相当于提高了型宽B,使得船舶复原力矩提高,抗外力矩能力提高,稳性提高,因此可以增设更大规模的风帆.文中通过合理配置母船与子船的适当流体间距,采用对母子风帆船最大横截面点仿真的分析方法,论证了母子风帆船的这些优点.母子风帆船是对古现代风帆船的一大提高和改进.预计此种船1年提供的平均推力,相当于改装前船舶消耗1年燃油总量后所能获得的平均推力.因此,采用该技术可以大幅度节能而且非常环保,经济效益和社会效益非常显著.

Research of Stability of Parent-subsidiary Wind Sailing Boat

This article do a research about the parent-subsidiary wind sailing boat and its energy-saving technologies and stability based on scientific analysis and comparison between parent-subsidiary wind sailing boat and common wind sailing. The parent-subsidiary wind sailing boat, which add a sub-ship on the basis of each side of a mother-boat and which is equivalent to the molded breadth B, improve the righting moment, capacity of resisting to external torque and stability of ship. So, larger sails can be added in this kind of ship. This article demonstrates the advantages of the parent-subsidiary wind sailing by rationally allocating the appropriate fluid spacing between the mother ship and sub-ship, u- sing analysis method which simulating to some points on the maximum cross-section of the parent-sub- sidiary wind sailing boat. We can say that the parent-subsidiary wind sailing boat has largely improved ancient and modern sailboat. Therefore, the method can greatly save energy and achieve very good en- vironment protection. So, economic benefits and social benefits of this method is very obvious.
