大型集装箱船弹振和颤振研究

摘要

With the rapid increase in the size of containerships, springing and whipping have become one of the key concerns of large containership design. From the aspects of ship motions and wave slamming, this paper studies the calculation method and model experiments of springing and whipping of large containerships. Study shows that springing and whipping have important influence on the structural strength and extreme strength of large containerships. Under severe sea conditions, the influence of springing and whipping is more crucial than that of the waves on the hull.%随着集装箱船尺度的迅猛增大，弹振和颤振已成为大型集装箱船设计中需要重点关注的问题。从船舶运动和波浪砰击的角度出发，对大型集装箱船弹振和颤振的计算方法和模型试验进行了研究。研究表明，弹振和颤振对大型集装箱船体的结构强度和极限强度都有重要影响，在恶劣海况下，弹振和颤振对船体的影响甚至已经超过波浪对船体的影响。
