摘要
穿浪双体船是近十几年开发的新船型,它因具有航速高、适航性好、布置宽敞等优点而备受关注。也由于该船型片体窄而高、连接桥宽而矮的特点,使连接桥的横向强度、扭转强度成为结构设计的关键技术,但目前关于穿浪双体船在波浪中的外载荷研究尚不多见。根据力学平衡原理,在研究总纵弯矩的基础上,采用数学积分的理论方法推导出穿浪双体船波浪外载荷分布及连接桥扭矩的计算方法。通过船模实验与实船计算结果进行比较,证明该方法是可靠、可信的,对实船设计有一定的指导意义及实用价值。
Wave-piercing catamaran is a new type of vessel developed in recent decade, and offers many advantages such as the high speed, good seaworthiness and more available space for arrangements, etc. Due to its high and narrow semi-body as well as the wide and low connection bridge, the transverse strength and torsion strength of the connection bridge become the critical factors in the structure design of the wave-piercing catamaran. But study on the external loads on the vessel in waves is seldom involved. The authors investigate the overall longitudinal bending moment of wave-piercing catamaran, and derive the external load distribution of the wave-piercing catamaran in the wave and the calculation method for torsion moment of connection bridge using mathematic integra- tion from the ＂mechanical balance principle＂. It is proved that the method is reliable and practicable method by comparing the calculated result of a real vessel with the model test result.
