摘　　要：本文通过十多个球首设计、试验和分析研究，为16000吨多用途货船的基本线型找到了一个较好的SV形球鼻首，其相对突出长度（l/lpp）为4，1％，相对宽度（b/B）为18．5％，相对浸沉深度（hp／T）为50％，横截面积比（Ab／AM）为10．3％。这些球鼻首参数对方形系数为0．73左右的中低速散装货船较为合适，船的阻力有较大的减小，船速有较大的提高，特别在轻载与压载状态增益更为明显。Based on the model tests of more than ten types of bulb bow, a good SV shaped bow with a relative protruding length l/Lpp=4.1%,relative breadth b/B=18.5%,relative immersion depth hp/T=50% and relative sectional area Ab/AM=10.3% is chosen for a low or medium speed multipurpose cargo vessel with a block coefficient of around 0.73 It has been found that with this pro posed bulbous bow,the resistance at drafts correpsonding to loaded,light load and in ballast condition were reduced,thus speeds increased
