摘要
以船舶非桁架结构形式的全封闭型桅杆作为研究对象，利用三维有限元方法，对其固有频率及振形进行了较为详细的数值分析，获得了关于这种复杂结构形式桅杆振动特性的有意义的结果．
With the totally enclosed masts of non truss structure for ships as the study object, numerical analysis of the natural frequencies and modes of the vibration of the masts are carried out using 3 D finite element method. Meaningful results of the vibration behavior of the masts with such complicated structure are obtained.
