摘　　要：通过试验途径研究了五体船的阻力性能特性,以及五体船后侧体型线形式、位置改变、对称形式、排水量改变、长宽比改变对阻力的影响.结果表明:侧体应该选用艉部过渡平缓的型线;后侧体靠近主体艉部位置较优;采用不对称后侧体的情况不能降低总阻力;减小后侧体排水量能有效降低总阻力;试验中后侧体长宽比的变化对总阻力没有明显影响;前侧体有静水吃水时增加了阻力;五体船型阻力性能大大优于单体船型.Through an experimental method the pentamaran resistance characteristics were studied. The molded line type, position, symmetry, displacement and the L/B value of the aft sponsons＇ influences upon the resistance were examined. The results show that the sponsons should use conventional molded line; the aft sponsons should be near to the main hull stern; asvmmetric aft sponsons do not reduce the to tal resistance; reducing the displacement of aft sponson5 can effectively reduce the total resistance; the aft sponsons＇ L/B does not influence the total-resistance apparently; the case of fore sponsons with still water displacement decreases the resistance performance; the best plan in the present experiment has advantage resistance performance over conventional ship.
