摘要: 以舰船筒型结构的全封闭型隐身桅杆为研究对象,利用 SCADA III数据采集器及 CADA X信号分
析系统和相关设备对其进行强度与振动试验,用试验获得的数据与有限元计算的结果相比较,从而验证三
维有限元法的可靠性。同时获得了一些关于这种复杂结构形式的桅杆在舰船不同纵(横)摇角、周期及桅
杆压载情况下,结构强度有意义的研究成果,为隐身桅杆的设计提供参考。

Abstract: W ith the totally enclosed and body concealed mast as the study object, the strength and vibration
experiment for the mast is carried out p rimarily using SCADA III data collecting imp lement and CADA X signal
analysis system and relative device . Reliability of 3 D finite element method is verified parison with data
attained from the test and calculated results obtained from FEM. Some meaning results of the strength of the mast
when ship is in different angle of trim (or heel) , different cycle of p itching(or rolling) and the different load on the
mast are obtained which may do some help to the mast design.
Key words: totally enclosed and body concealed mast; strength and vibr
