【摘要】 本文分析了双体船在任意浪向中航行时的运动和受力.得出了表征双体船运动方程中各流体动力和扰动力的数学表达式.这些数学表达式不仅适合于双体船,同样可用于单体船,也可推广应用于多体船。 在分析双体船的流体动力和扰动力时,除了考虑航速和末端项的影响外,还考虑了有航速情况下两片体间的流体动力干扰。对于双体船,这些流体动力干扰不容忽略。更多还原

【Abstract】 This paper analyzes the motions of a catamaran advancing at a constant speed in arbitrary heading waves. Mathematical expressions are derived for hydrodynamic coefficients and exciting forces. They apply not only to catamaran, but also to monohull, and can be extended to multihull. In analyzing hydrodynamic and exciting forces, hydrodynamic interactions between the two hulls are considered in addition to the effect of forward speed and aftermost section. These hydrodynamic interations should not be neglected for the motions of catamaran.更多还原
