| 摘 要： | 三体船片体位置优化的工作量很大,不仅要考虑片体间的横向距离,也要考虑片体间纵向距离.为快速优化三体船的片体位置,基于Noblesse细长体理论,按照一阶Kochin函数的表达式,在指数函数展开分离变量方法的基础上,本文推导了三体船兴波阻力的计算公式,并根据这些公式实现了三体船兴波阻力的快速计算.数值计算与模型试验相吻合.数值计算结果和模型试验结果均显示,三体船的片体位置对兴波阻力有很大影响.

| Abstract: | It is a kind of hard work to optimize a trimaran configuration, because the distance in longitudinal direction and the distance in transverse direction between the hulls should be taken into account in the mean time. Based on Noblesse's Slender Ship Theory, where the variables are separate by expanding exponential function, the wave resistance formulae of a trimaran are obtained.The wave resistance can be calculated rapidly with these formulae.The numerical results coincide with that of the model test. Both the numerical results and the model test results show that the longitudinal distance and the transverse distance have great influence on the wave resistance of a trimaran. |
