穿浪双体船横弯矩计算方法研究

Basic research of calculation of transverse bending moment for wavepiercer

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横向载荷研究尚不多见。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在波浪中的横向载荷分布及横向弯矩的计算方法。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。

Wavepiercer is a new type of vessel developed in recent ten of years, with many advantages of the high speed, good weatherworthiness and big available arrangements, etc.Due to the high/narrow demi-body and the wide/low connection bridge the transverse strength and torsional strength of the connection bridge has become a critical factor of the construction design of the wavepiercer.Author makes a relatively through inquiry into the overall longitudinal bending moment of wavepiercer, and derives the transverse load distribution of the wavepiercer sailing in sea and the calculation of transverse bending moment using mathematic integration from the“mechanical balance principle”.It had been proved a reliable and trusty method by comparing the calculation result from a real vessel with the model test of this vessel, which is valuable in guiding the design for the wavepiercer.
