摘要
对船舶上层建筑整体振动有限元建模方法进行研究,讨论了不同计算模型、边界条件、附加水质量以及装载情况对上层建筑整体振动固有频率的影响。通过对76000t油轮、110000t油轮、8000TEU级超大型集装箱船、174000t散货船、30000t散货船和11800t散货船六条船的计算,对上层建筑整体振动有限元建模问题得到了一些有益的结论。
As to the finite element modeling of the superstructure＇s overall vibration, the influence of various models, boundary conditions, additional water mass and loading conditions on the natural frequency of superstructure is studied in this paper. Taking the 76 000t oil tankers, 1 I0 000t oil tankers, 8 000TEU super container ships, 174 000t bulk carriers, 30 000t bulk cartier and 11 800t bulk carriers as examples, we get some meaningful conclusions for finite element modeling of the superstructure＇s overall vibration.
