摘要
针对船体振动预报中建模工作量大、计算分析周期长等问题,结合油船的结构特点,提出组合模型在油船振动分析中的应用,同时讨论了组合模型的模拟方法。以某11.5万吨油船为例,与全船三维模型进行对比,从船体梁振动特性、上层建筑振动特性以及船体振动响应等方面研究讨论了组合模型在振动分析时的要点及分析精度,并证实了组合模型用于油船各设计阶段振动分析的可行性。
For the problems of heavy modeling workload and long calculation period in ship vibration prediction,combined with the structural characteristics of oil tanker cargo hold,combined model for oil tanker vibration analysis is proposed.The simulation method of combined model is discussed.Tanking a 115,000 DWT oil tanker as an example,compared with the whole ship 3 D model,the key points and analysis accuracy of combined model in vibration analysis are studied from the aspects of ship hull characteristics,superstructure m characteristics and response.And it is proved that the feasibility of the combined model is applied to the vibration of oil tanker in design stage.
