摘要
筒状桅杆在现代船舶上已得到越来越广泛的应用。由于结构形式的改变,其动力学性能也随之发生变化,对船舶的性能产生了很大影响。因此,有必要对筒状桅杆的振动模态进行分析研究。本文以某船的筒状桅杆作为主要研究对象,用大型有限元分析软件ANSYS建模并进行了模态计算,并用实验结果进行验证,结果令人满意。
Tubular masts have been used in modern warships more and more in recent years. As the transformation in the structure because of stealthy performance, the dynamics property has also been changed and exerted a tremendous influence to ship performance. So it is necessary to make analysis and research to the vibration mode of tubular masts. In the paper, tubular masts of a ship has been chosen as a research object, modal analysis has been done by use of finite element software ANSYS and a satisfactory result has been gained.
