摘要:以舰船棱柱型结构的全封闭型隐身桅杆为研究对象,利用比利时 LMS 公司的 SCADAIII 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利用 ANSYS 有限元计
算软件计算的结果相比较,从而验证三维有限元法的可靠性. 通过试验和计算对比,发现有限元计算和试验结
果间的误差很小,并且在相同周期条件下,应力值随摇摆角度的增加而增加,在相同摇摆角度的条件下,应力值
随周期的增加而减小. 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,结构强度的有一定意义的研究成果,为隐身桅杆的设计提供参考.

Abstract :With a totally enclosed and prism concealed mast as the study object , a structure intensity experiment
for the mast is carried out primarily using SCADAIII data collecting system and LMS CADA X signal analysis
system. The reliability of the 3D finite element method using ANSYS software is verified parison of da
ta obtained from the test and calculated results obtained from FEM. From this , we can find the error between
the finite element method and the test is very small. It is also found that in the same cycle the value of stress in
creases along with the increase ang
