冰区航行船舶推进器特殊性分析

Analysis on the particularity of propulsor of ice-going ships

  • 摘要:
      目的  推进器是船舶航行过程中推力的来源,其设计是船舶设计过程中的关键部分。由于工作环境不同,冰区航行船舶推进器与敞水船舶推进器相比在载荷分析和设计上差别较大。为给冰区航行船舶推进器的设计提供依据,
      方法  针对冰级桨的水动力特性、冰载荷以及空泡等性能的特殊性予以分析。
      结果  结果显示,在冰区航行时,海冰的存在会导致船舶推进器遭受更大量级的载荷,并且在低进速时易引发推进器的空化现象,产生强烈的噪声。
      结论  研究表明,设计冰级桨时要特别注意冰载荷的量级和空化效应,并考虑采用铜合金或奥氏体钢等耐低温材料建造推进器。

     

    Abstract:
      Objectives  The propulsor is the source of propulsion during the ship's navigation, and its design is also a key part of the ship's design process. Due to the different working conditions, propulsors of ice-going ships differ greatly from propulsors of open water vessels in terms of load analysis and design. In order to provide a basis for the design of ice-going ship propulsor,
      Methods  this paper analyzes the special hydrodynamic characteristics, ice load and the cavitation performance.
      Results  Through analysis, it is found that when a ship sails in ice region, the presence of sea ice will cause the propeller to sustain more loads and easily cause cavitation of propeller at low speed, resulting in severe noise.
      Conclusions  The analysis shows that when designing ice-class propellers, special attention should be paid to the magnitude of ice load and the cavitation effect, and the construction of propellers with low temperature resisting materials such as copper alloy or austenitic steel should be considered.
