极地船舶吊舱推进器的功率匹配研究

Study on power matching of podded propulsor for polar ships

[目的]为了提高吊舱推进极地船舶设计的针对性和适用性,需开展功率匹配研究。[方法]根据国外各类冰级划分规则和实船调研结果,明确不同冰级船舶在北极的四季可航范围。基于Lindqvist公式计算3艘极区典型吊舱推进船舶的冰阻力,从而估算吊舱推进船舶的需要功率。通过调研市场上较成熟的吊舱推进器产品,建立一种极地船舶吊舱推进器的初步选型方法。[结果]结合目前主流吊舱推进器的单机功率和布置型式,得出了各类船型在不同冰级下的功率匹配结果和初步选型建议。[结论]研究成果可为设计阶段的吊舱推进器选型工作提供参考。

[Objective]To enhance the pertinence and applicability of polar ships with podded propulsion design,the power matching problem should be researched.[Methods]Based on the overseas classification rules of ice classes and the results of ship investigation,the seaworthiness ranges of ships in different polar classes over the four seasons of the Arctic are confirmed.Based on the Lindqvist formula,the ice resistance levels of three typical podded propulsion ships in the polar regions are calculated,and the required power of a podded propulsion ship is obtained.Based on an investigation of mature pod thruster products on the market,a preliminary selection method for the pod thrusters of polar ships is established.[Results]Combined with the current single machine power and arrangement types of pod thrusters,the power matching results and pre-liminary suggestions for the selection of various ship types under different ice levels are obtained.[Conclusion]The results of this study can provide references for thruster selection in the design stage.
