摘　　要：利用有限元法对13500TEU集装箱船绑扎桥的振动特性进行研究。基于英国劳氏船级社针对绑扎桥振动评估的相关指南中的振动部分,评估绑扎桥的固有频率和结构振动响应。建立整船绑扎桥振动分析模型,研究超大型集装箱船绑扎桥的典型振动模态和固有频率特性,找出不同位置绑扎桥的受迫振动响应对应的激振力成分。针对英国劳氏船级社指南中有关模型范围、边界条件、评估衡准和激振源等的内容,对该绑扎桥振动分析模型的有效性进行深入论证,并给出船厂的建议。Finite element method is used to study the lashing bridge vibration characteristics of a 13500 TEU container vessel.The natural frequency and structural vibration responses of the lashing bridge are assessed according to the Procedure for the Assessment of Container Ship Lashing Bridge Structures issued by Lloyd’s Register.The lashing bridge vibration analysis model for entire ship is established to study the typical vibration mode and natural frequency characteristics of the super large container vessel,and the components of excitation forces corresponding to the forced vibration responses of the lashing bridge at different locations are discovered.The model extent,boundary condition,assessment criteria and excitation sources in the guidelines are analyzed in detail,and some suggestions for shipyard are proposed.
