摘　　要：[目的]为保障科考人员安全和科考设备性能,需开展极端海况下的科考船砰击载荷和液体飞溅特性研究。[方法]以“中山大学”号科考船为例,基于光滑粒子流体动力学(SPH)方法,建立δ-SPH流固耦合动力学模型,进行极端海况下的SPH数值模拟,从而预测船体受到的砰击载荷、甲板上浪及液体飞溅程度,并分析其影响因素和物理机制。[结果]仿真结果表明:波高越大、波长越接近船长时,船体受到的砰击载荷越大,甲板上浪和液体飞溅越明显。[结论]研究成果可为极端海况下操纵与控制科考船、保障科考人员安全及科考设备性能提供参考。[Objective]Scientific research vessels may encounter extreme sea conditions during research voyages.It is of great significance to study the slamming load and fluid splashing characteristics of scientific research vessels under extreme sea conditions to ensure the safety of scientific personnel and the performance of scientific equipment.[Methods]The article takes the Sun Yat-sen University scientific research vessel as an example,based on the smoothed particle hydrodynamics(SPH)method,establishes a δ-SPH and fluid structure coupling dynamic model,and carries out SPH numerical simulation of the scientific research vessel encountering extreme sea conditions.It predicts the slamming load,the degree of deck wetness and fluid splashing under extreme sea conditions,and analyzes its influencing factors and physical mechanisms.[Results]The results indicate that as the wave height increases and the wavelength approaches the captain,the slamming load on the hull increases,and the degree of deck wetness and fluid splashing becomes more significant.[Conclusion]The results provide a basis for maneuvering and controlling scientific research vessels under extreme sea conditions,ensuring the safety of personnel and equipment performance on scientific research vessels.
