大型邮轮乘员多达几千人，其运营安全性及乘坐舒适性至关重要，有必要对其耐波性能开展针对性研究。本文以数值模拟与模型试验相结合的方法研究某大型邮轮的相关耐波性能，数值计算应用三维线性时域势流理论，试验模型为1∶55缩尺比制作的水面自航模型。首先对比分析邮轮计算结果与试验数据，验证研究方法的可靠性，然后进一步依据相关耐波性衡准评估了邮轮在不同航速、浪向、海况下邮轮的安全性与舒适性。结果表明：大型邮轮在5级及以下海况可满足舒适性标准，在更高海况下须避免在浪向30°及90°条件下航行；在6级海况、航速不超过15 kn时，大型邮轮安全性与舒适性亦符合标准。
There are thousands of passengers in large-scale cruise ships, and its operation safety and riding comfort are very important, so it is necessary to carry out targeted research. In this paper, the seakeeping performance of a large cruise ship is studied by combining numerical simulation and model test. Three dimensional linear potential flow theory in time domain is applied in the numerical calculation. The experimental model is a self-propelled model with a scale of 1∶55. Firstly, this paper compares and analyzes the data of cruise calculation and test, and verifies the reliability of the research method, and then further evaluates the safety and comfort of the cruise ship under different speed, wave direction and sea conditions according to the relevant seakeeping criterion. The results show that the large cruise ship can meet the comfort criterion in the sea state 5 and below, and it is necessary to avoid sailing in the conditions of 30° and 90° in the wave direction under the higher sea conditions; Its safety and comfort also meet the standard when the sea condition is level 6 and the speed is no more than 15 kn.
