本文以一艘8600 TEU大型集装箱船为研究对象，对其应力监测数据进行了分析，作为揭示大型集装箱船在实际航道中鞭梢响应的初步尝试。测量持续了大约五年，并使用大量的数据，我们调查了海况和操作条件如何影响鞭打响应。此外，将船体中部纵向应力分解为船体梁的垂向弯曲、水平弯曲、扭转和轴向分量。之后，我们发现扭转和水平弯曲分量的鞭梢幅度远小于垂直弯曲分量的鞭梢幅度。未来的研究将包括分析大量的数据，分析其他传感器数据，以及各种振动响应模式对极限强度和疲劳强度的影响。所得结果对今后大型集装箱船的设计和营运具有一定的参考价值。
In this study, as a preliminary attempt to reveal the whipping response of large container ships in actual seaways, the stress monitoring data of an 8600 TEU large container ship were analyzed. The measurement lasted approximately five years, and using a large amount of data, we investigated how the sea state and operational conditions affected the whipping response. In addition, the midship longitudinal stresses were decomposed into hull girder vertical bending, horizontal bending, and torsional and axial components. Thereafter, we found that the whipping magnitude on the torsional and horizontal bending components is much smaller than that on the vertical bending component. Future research would include the analysis of a larger amount of data, analysis of other sensor data, and effects of various patterns of vibrational response on the ultimate strength and fatigue strength. The obtained results will benefit the future design and operation of large container ships for safer navigation.
