天津1号大型助航浮标结构研究

THE STRUCTURAL STUDY OF THE LARGE NAVIGATIONAL AID FLOATING LIGHT TJ-1

介绍一种总高12.7m,壳体外形直径10.4m,助航灯射程10海里,具有抗冰能力、全年连续工作的助航浮标天津1号(TJ-1),并论述了该浮标结构选型、冰荷载对浮标的作用、塔架结构与壳体结构受力分析及其结构研究等问题。

China's first large navigational aid floating light TJ-1 was succesfully developed on Dec 1986. The total height of this floating light is 12.7m, and diameter of its shell structure is 10.4m, Range of visibility of light itself is 10 n miles. The floating light with a capacity of ice resistance is provided for continuous operation all the year round. This paper describes the selection of the structure types, the effect of ice loading on the floating light, the analysis of the tower structure in moving condition to be subjected to the forces, the strength and self-vibration character of the tower structure, and the study of the shell structure of the floating light, etc.
