【摘要】 本文对横摇运动的非线性方程的求解引入两种方法:迦辽金法和Cell—to—Cell映射法。同时对迦辽金法求得的解进行了稳定分析。通过对“长江口交通补给船”在规则波的运动进行计算,并把结果与试验结果作了比较,总的说来还比较一致。更多还原

【Abstract】 Two methods,Galerkin’s method and Cell-to-cell mapping method, are adopted in the solving of non-linear e-quation of ship rolling. The stability analysis is performed to the solution obtained by Galerkin’s method. The ealculated results of the motion of "Yangtze Mouth Communications and supply ship" in regular waves are compared with experimental data. The agreement is generally satisfactory.更多还原
