Research on impedance characteristics of cantilever base for typical ship

基于阻抗分法探索悬臂型基座的机械阻抗特性,借助有限元软件数值分析典型船体悬臂型基座的阻抗特性,以及基座各结构参数对其机械阻抗的影响规律;在此基础上,基于阻抗失配原理开展了悬臂型基座结构参数优化研究,最终形成一套较准确的船体基座阻抗分析方法,且具有较好的工程应用价值。

Based on the impedance analytic method ,the mechanical impedance characteristics of the cantilever base are examined,and those of the typical cantilever base for a ship are analyzed through FEM software,along with the influences of structural parameters. Furthermore ,the optimization research of structural parameters is carried out based on the impedance mismatch principle. Finally ,a set of accurate impedance analytic methods for the hull base are built,which provide the better engineering value.
