大型及超大型油船总体振动分析方法研究

通过引进双梁模型和推导出的三梁模型对大型油船的总体振动特性进行了分析研究；同时将多梁模型与常用的单梁模型、经验公式进行了比较。结果显示，多梁模型在分析大型或超大型油船总体振动方面较单梁模型有较好的实用价值，特别是在高阶振动时有更好的逼近。这为大型船舶总体振动预报提供了一个实用的方法。

Study of hull vibration for large tanker

The hull vibration of large tanker is studied on the basis of introducing double beam model and a tri beam model is then proposed. By using both the multi beam model and single beam model, the vibration calculations of a ship are performed. The results with the multi beam models show some more favorable features than those with single beam model. Based on these studies, it is considered that the tri beam model will be more suitable for hull vibration analysis, especially in higher mode situation.
