三体船方案优化布局的阻力计算与试验研究

本文利用Michell薄船理论，计算了对应侧体不同纵横向位置时三体船的阻力，并将计算结果与模型试验结果进行了比较。阻力计算结果与试验结果比较接近，真实反映出了随航速的变化，三体船阻力较小时侧体布局的规律，与国内外相关文献发表的三体船的这种侧体布局规律一致，Michell理论用于三体船以及当前出现的五体船型式的方案优选还是可靠的。

Resistance study on alterative layouts of the trimaran hull configuration

The resistances of the layouts of trimaran with different longitudinal and transverse positioning of the side-hulls were calculated based on the Michell's thin-ship theory and compared with the experimental results.The results show that the calculated prediction is closing to the model experimental results and can indicate the rule of the resistance relating to arrangement of side hulls and the ship speed.The analyzed rule in this paper is also consistent with that the other literatures presented.It shows also that the Michell theory is applicable for evaluating the configuration of the trimaran hulls.
