摘要:
为保证南极磷虾船有足够的强度抵抗南极海域冰区的冰载荷,同时具有较经济的结构重量,对高强度船用钢开展不同温度下的力学性能试验,选用合适的参数对极地船舶结构进行优化研究;并以规范为基础计算设计冰载荷,对极地船舶冰带结构进行优化设计研究。研究结果表明,在环境温度由20℃降到-60℃情况下,材料的抗拉强度和屈服强度均增强,因此在进行结构优化设计时,可以选取高强度钢常温下的力学性能参数进行计算。设计船舶为船艏破冰,根据《极地船舶指南》,以船艏纵桁、肋骨、中内龙骨规格和外板的厚度作为优化参数,以质量最小为优化目标进行优化,选取质量最轻的方案,获得最经济结构设计。
Abstract:
In order to ensure that the Antarctic krill vessel has enough strength to resist the ice load, and in the economy,it has appropriate structural weight. In this paper, the mechanical properties of high-strength steel at different temperatures are studied by selecting appropriate parameters to optimize polar vessel. The ice load is calculated and designed on the basis of the rules, and the optimal design of the ice belt structure of polar vessel is studied. The test results show that the tensile strength and yield strength of the material increase when the environment temperature drops from 20℃ to -60℃. Therefore, the mechanical properties of the high-strength steel at normal temperature can be selected for calculation when the structural optimization design is carried out. According to the "Polar Ship Guide ", the ship is designed to break the ice for the bow. The size of the bow girder, ribs, keel and thickness of the shell plates are taken as the optimization parameters, and the optimization objective is to optimize the vessel with the minimum weight. The scheme with the lightest weight is selected to obtain the most economical structure design.
