摘　　要：采用线性兴波阻力计算方法,结合CFD通用软件模拟,对比分析前后片体横向间距不等五体船、五片体简单叠加及前后片体横向等间距五体船阻力特性,研究侧体布局对兴波阻力影响的规律及其减阻优化效果。研究结果表明,五体船前后片体分别纵向靠近首尾布置,可以扩大有利兴波干扰速度范围,高速段侧体横向偏内可以获得较佳阻力值,并且片体纵向位置的改变相比横向位置的变化,对阻力值影响更大。Both the linear wavemaking resistance theory and the CFD simulation methods were used to analyze pentamaran resistance with equal and unequal offset distance of before and after demihulls with the sum of five hulls resistance,and the influence of the demihulls layout on wavemaking resistance and its corresponding resistance reduction optimization effect were studied. The results showed that demihulls respectively lay more before or after could expand favorable wave interference range,and demihulls lay inward can obtain better resistance values,and the change of longitudinal position had greater effect than lateral position.
