摘　　要：论文采用基于RANS方程的数值计算方法,对"探索一号"科考船安装多波束测深仪后的船阻力及多波束测深仪的气泡性能进行数值模拟;给出了多波束测深仪不同安装方案下的船舶阻力性能计算结果,同时结合自由面波形图、船体表面压力图以及流线图对计算结果进行分析;并提出一种气泡性能分析方法——流线监测法,采用该方法对各个方案多波束测深仪的气泡性能进行对比;最终获得多波束测深仪不同安装方案下的科考船阻力性能与多波束测深仪气泡性能之间的关系,为"探索一号"科考船多波束测深仪的安装设计提供技术支撑。In this paper, a numerical method based on RANS equations is used to simulate resistance performance and bubble performance of the ＂Exploration 1＂ scientific research ship. Resistance performances under different installation schemes are given together with consideration of free surface waveform, pressure diagram of the hull surface and the flow chart. A method, called as streamline monitoring method, for evaluating bubble performance is proposed, and bubble performances of different schemes of the acoustic equipment are compared. The research may provide technical suggestions for the design of the acoustic equipment for the ＂Exploration 1＂ scientific research ship.
