三体船横摇运动性能三维数值研究

该文运用商业软件HydroStar对在横向规则波中航行的三体船的附体位置对其横摇性能的影响进行了数值计算研究.通过计算,本文得到了十二种不同的附体配置方案在三个航速下横摇频率响应函数曲线.计算结果表明:三体船的横摇性能主要受其附体的横向位置影响,附体纵向位置对横摇性能的影响要远小于横向位置的影响,在考察的范围内,航速对三体船的横摇性能影响微弱.

Three-dimensional numerical calculation of roll motion of a trimaran

The roll motion of a trimaran ship form in regular beam waves was studied based on data calculated by Hydrostar, a version of hydrodynamic software developed in Bureau Veritas. Effects of outriggers positioning on the roll motion at three speeds were investigated via positioning the outriggers at twelve different locations along the ship length and with different intervals between main-hull and outriggers. Numerical results show that: 1) the trimaran's roll motion is mainly affected by the outriggers' lateral position;2) the effect of outriggers' longitudinal position on roll motion is much feebler than that of lateral position;3) the trimaran's sailing speed affects very slightly its roll motion in investigated speed range.
