高速三体船兴波阻力与片体布局优化研究(英文)

Investigation of Wave Resistance on High Speed Trimarans

本文据线性兴波阻力理论推导了辅船体与主船体水下体积不相等情况下的兴波阻力计算公式,据此以数学船型作为片体对高速三体船片体兴波干扰规律、兴波阻力曲线规律进行了研究,并采用简单枚举与等值线图谱相结合的方法对片体布局优化问题进行了探讨。

Based on the linear wave resistance principle, the wave resistance formula was established for the high speed trimarans with a main center hull and two small outer hulls. By present wave resistance formula, the regulation of the wave interference effect from each piece hulls, and the trend of the wave resistance curve were investigated; in addition the method for optimizing the outer hull position from the point of view of reducing wave resistance was studied, incorporating the contour graph method and simple enumeration method.
