铝合金桅杆结构强度和振动计算分析

Computational Analysis on the Vibration and Structure Strength of Aluminum Alloy Mast

以某改装船桅杆设计为例,通过对桁架式铝合金桅杆在不同工况下的结构强度和振动进行有限元分析,阐述桁架式桅杆结构强度校核和振动预报的一般方法,为该船桅杆结构的设计和应用提供理论依据。该计算方法可为其他桁架式桅杆的有限元分析提供参考。

Taking the mast of a refitted ship as example,a finite element analysis is performed on the vibration and structure strength of the truss type aluminum alloy mast under different conditions to elaborate the general method for the strength check and vibration prediction of this type of mast,which provides the theoretical basis for the design and application of the mast structure.The computational method can provide reference for the finite element analysis of other truss type masts.
