摘　　要：高速三体船以其优良的减阻性能、耐波性和稳性而具有广阔的军事和商业应用价值。尽管已有大型实船付诸应用,但高速三体船型的兴波阻力预报和减阻设计问题并未解决,而这又是高速三体船实际应用的重要环节。采用帐篷函数法进行高速三体船的片体构型设计,并据此计算各船型参数。将改进的线性兴波阻力数值算法应用于高速三体船的兴波阻力计算,根据模型试验结果,验证了计算方法的有效性。High speed trimarans, with their excellent performance in drag reduction, sea-keeping and stability, have wide application outlook in both military and civil markets. Despite the fact that high speed tri- marans have already been widely applied globally, their wave-making resistance forecast, a key factor in the design process, have not been so rigorously investigated. This paper employs the tent function to design the demihull structure of high speed trimarans, through which a variety of ship form parameters are calcu- lated. Moreover, the improved linear wave-making resistance calculation algorithm is adopted, and the ob- tained results for high speed trimarans are compared with model test results, which validate the proposed method in the preliminary design stage.
