摘　　要：为得到一艘新型双体无人测量艇的阻力性能和经济航态,分别利用模型试验、经验公式和计算流体力学(CFD)方法对该艇进行阻力预报和阻力成分分析.运用CFD方法进一步探究工作航速下船体的不同重心纵向位置对船体阻力、纵倾和船周波形的影响,还为多波束声学设备选取了合适的船体安装位置.结果表明,CFD方法能精确完整地预报双体测量艇从低航速排水到高航速滑行的航态变化和阻力特性,而经验公式法主要适用于测量艇航速较低(F_(r▽)<1.5)时的阻力预报.在4~6 kn测量航速下,该艇的阻力经济航态约为尾倾1.4°,此时在片体间距离船尾约0.3~0.5个船长位置处存在一个相对稳定的高液位区域,适合作为无人测量艇多波束声学设备的安装位置.In order to obtain the resistance performance and economic navigation posture of a new unmanned survey catamaran,a calm water resistance simulation of this catamaran is conducted by model tests,the empirical formula method,and the computational fluid dynamics(CFD)method.Further,the CFD method is used to explore the influence of different longitudinal positions of the center of gravity on the hull and perimeter waveform,and a suitable installation position is selected for the multi-beam acoustic equipment.The results show that the CFD method can accurately predict the navigation posture and resistance at all speeds,while the empirical formula method is mainly suitable when the speed is low(F_(r▽)<1.5).At the speed of 4 and 6 kn,the economic navigation posture is at a tail tilt of 1.4°.At this time,there is a relatively stable high water level area between the pieces of about 0.3 to 0.5 times of vessel length from the stern,which can be used as a suitable installation position for multi-beam acoustic equipment.
