摘要
以三体船船模为研究对象,通过理论研究、船模试验、数值模拟三者相结合的方式,对其快速性进行研究。在快速性试验的基础上,笔者基于ISIGHT-FD软件平台,建立数学模型,从船舶阻力和船舶推进相结合的角度出发,选用遗传算法建立辨识系统,分析该三体船船模的片体布局对其快速性的影响以及船、机、桨的配合情况。最终,通过绘制的剩余阻力曲线和敞水效率曲线,验证辨识结果并加以预报。
In this paper, the trimaran model is studied, and its rapidity is studied by means of theoretical study, ship-model test and numerical simulation. Based on the rapid test, the author established mathematical model by ISIGHT - FD software platform, from ship resistance and ship promote combined angle of genetic algorithm （GA） is used to establish a system identification, analysis of influence of the trimaran ship model sheet body layout of the fast and ship, engine and propeller with the situation. Finally, the residual drag curve and the open water efficiency curve are drawn, and the identification results are verified and predicted.
