小型高速SWATH船下体型线研究

根据帐篷函数法和切片理论分别编制了SWATH船的阻力、纵向运动理论预报程序,理论计算值与试验数据相一致.针对小型高速SWATH船主机置于下体后,下体型线的3种典型变化情况,理论分析了下体型线改变对SWATH船的阻力及纵向运动性能的影响,并对其做出综合评价.

Study on Lines of Lower Hull of Small-sized High-speed SWATH Ship

In the paper, some theoretical predicti on programs on resistance and longitudinal motion of a small-sized high-speed SW ATH ship are set up by using the tent function method and strip theory, respecti vely, and their results are confirmed by experimental data. In view that the sma ll-sized high-speed SWATH ship has its main engine in its lower hull, its lowe r hull needs to be changed. The effect of three typical changed lines on its res istance and longitudinal motion is theoretically analyzed, and a comprehensive e valuation on the lines is put forward.
