摘要
本文就三种不同横剖面形状的高速双体船(Fr=1.1)的模型阻力试验资料,分析了船型、间距比和Froude数对双体船阻力的影响,文中提出了把双体船片体间波系干扰分为横波干扰和散波干扰的分析方法,另外还考虑了当片体间距相对小、航速相对高时,片体间发生的流动阻塞现象。根据片体间波系干扰分析方法并结合试验观察,本文推荐简易有效的片体间无干扰间距的计算式和片体间流动阻塞衡准式。
Based on the data of resistance experiments of high-speed catamarans of three different forms, a discussion is made on the effect of hull form, demihull spacing ratio and Froude number on the resistance and an analytic method in which the interference of wave systems generated by catamaran is subdivided into transverse wave interference and diverging wave interference is proposed. The flow blockage between demihulls is to be considered when the demihull spacing is small and the catamaran speed is high Finally, a simplified formula for calculating the demihull spacing which does not produce interference and a criterion for the flow blockage are given in the paper.
