摘要: 舰船耐波性不仅是衡量舰船总体性能的重要指标，也对舰船上人员晕动症的发生有直接影响，因此，良好的耐波性设计是保障舰员舒适度和绩效的基础。采用切片法理论编写耐波性计算程序，对DTMB 5415标模进行耐波性计算，得到在迎浪中不同航速下船艏、重心处的垂向加速度响应，分析DTMB 5415标模对应的驱逐舰升沉运动时垂向加速度对人因中晕动症造成的影响，给出驱逐舰耐波性与人因中晕动症的数值关系。结果表明：船艏和重心处垂向加速度理论计算结果正确，准确度满足晕动症预报的要求；计算所得晕动症发生率规律合理，可作为驱逐舰船型晕动症发生率分析和预报，以及人因改善的资料。Abstract: Seakeeping is not only an important indicator of the overall performance of a ship, it also has a direct impact on the occurrence of motion sickness among ship personnel; as such, a good seakeeping design is the basis for guaranteeing the crew's comfort and work performance. In this paper, a seakeeping calculation program using the theory of the strip method is written to calculate the seakeeping of the DTMB 5415 standard model, and the vertical acceleration response at the bow and the center of gravity in head waves and under different speeds are obtained. Next, the effects on motion sickness of the vertical accelerations of DTMB 5415 corresponding to the destroyer's heaving are analyzed, and the numerical relationship of motion sickness with the destroyer's seakeeping performance is obtained. The results show that the calculated vertical accelerations at the bow and center of gravity are correct, the accuracy of which satisfies the requirements of motion sickness prediction; and the calculated regularities of the motion sickness are reasonable, and can be applied to analyze and predict the incidence of motion sickness on a ship, as well as to improve human factors in the hull form design of destroyers.
