极地航行船舶概念设计多目标优化方法研究

摘要

随着北冰洋海冰的融化，北极航线因其带来的巨大商业利益而变得越来越重要。因此，高效环保的绿色极地航行船舶研发显得尤为迫切。本文围绕极地航行船舶的冰/水动力特性，提出了以破冰航行效率作为衡量破冰能力的技术指标，进行了破冰航行效率的理论推导，建立了以破冰航行效率、EEDI 和相对回转直径为目标函数的综合性能多目标优化模型，并以一艘油船为例开展了优化研究，为进一步确定极地船舶的主尺度和船型优化提供了方法。%There is an urgent need for research on and design of high efficient and green ship sailing in the Arctic regions. Hydrodynamics performance of an ice-going ship at iceo-ice conditions is focused on, while efficiency of ice-breaking sailing is put forward and deducted. A multidisciplinary optimization model of ice-going ships at iceo-ice conditions is established, which includes three objective functions:EEDI, relative turning diameter and efficiency of ice-breaking sailing. It is shown from example of A super oil tanker is calculated. Through this numerical example, the reasonability, practicality and effectiveness of the optimal method are verified.
