Design and simulation analysis of thruster of water jet of high speed shipping

随着喷水推动技术和喷水推进器制作技术的发展,越来越多船舶采用喷水式推进方式。基于Ansys仿真软件,对进水流道、叶轮和导轮、喷泵喷嘴以及船舶倒车机构进行设计原理分析和仿真研究。结果表明,进水流道、叶轮和导轮、喷泵喷嘴以及船舶倒车机构对高速喷水动力推进器性能具有显著影响,优化结构尺寸能够提高喷水推进器性能。结合不同控制方法设计航向航速控制器,在航向航速稳定控制的基础上,提高船舶的适航性,为该类船舶的控制系统设计提供理论依据。

With the development of water jet propulsion technology and water jet manufacturing technology,more and more ships adopt water jet propulsion.The design principle analysis and simulation research of inlet channel,propeller and guide wheel,jet pump nozzle and ship reversing mechanism are carried out on the basis of Ansys.The results show that the inlet channel,propeller and guide wheel,jet pump nozzle and ship reversing mechanism have significant effects on the performance of water jet propulsion,and the optimization of structure size can improve the performance of water jet propulsion.The course and speed controller is designed combined with different control methods to improve the seaworthiness of the ship on the basis of stable control of course and speed,which provides a theoretical basis for the control system design of this kind of ship.
