| 摘 要： | 针对穿浪双体船航行纵倾随航速变化较为明显的特点,结合薄船理论和帐篷函数法,提出了一种计及艇体航行纵倾变化的穿浪双体船阻力预报方法.通过对某型穿浪双体船阻力的计算结果与模型试验结果的对比,考核了该预报方法的有效性,并得出穿浪双体船片体间距变化对阻力的影响规律,即片体间距越大,其兴波阻力、总阻力越小.研究表明,该方法能提高穿浪双体船的预报精度.

| Abstract: | The variation of trim of wave piercing catamaran(WPC) is obvious when its navigation velocity changes.A kind of resistance prediction method for WPC in the consideration of trim was pre-sented according to the thin ship theory and tent function.The resistance of certain WPC was calcula-ted with this method.The calculated result agrees well with the experimental result,which shows the validation of this method.Some meaningful conclusions were drawn through studying the influence of the hull space of WPC on i... |
