随着大型集装箱船的发展，斜浪条件下的扭矩载荷特性及其结构响应日益重要。以某大型集装箱船为研究对象，建立水动力湿表面计算模型和质量模型，研究基于扭矩传递函数和主要载荷控制参数的斜浪设计波参数确定方法，分析不同超越概率水平下扭矩计算值的规律。考虑典型斜浪参数和超越概率水平，分析水动力计算扭矩与船舶规范（ABS和HCSR）扭矩的差异及原因，提出集装箱船扭矩载荷计算与应用的建议。通过计算45°，60°和75°斜浪条件下的船体结构应力云图，识别斜浪作用下船体结构响应的关键位置，可作为大型集装箱船结构设计过程中船体梁扭转强度计算、舱口角隅设计、抗扭箱强度评估等的参考。
It is important to study on torque load characteristics and structural responses under oblique waves as the development of large container. This paper built up wet surface model and mass model based on a large container, and studied on how to determine the design wave parameters according to the torque response function and dominant load parameters. And we analyzed the relationship between the exceeding probability level and calculated torque. This paper worked on the torque's differences and its reason among dynamic load approach (DLA), American Bureau of Shipping (ABS) container rule and "Common Structural Rules for Bulk Carriers and Oil Tankers (HCSR)" considering the typical oblique wave parameters and exceeding probability level. This paper also gave some proposals on how to calculate and applicate the torque load for container ships. On this foundation, we chosen three wave conditions (45°, 60° and 75°) for further case study, and identified the key structural positions under oblique waves by calculating the stress distribution. In conclusion, the study of this paper is a good reference for structural design of large container, such as the torsional strength calculation of hull girder, the design of hatch corner and the strength evaluation of torsional box.
