本文根据海洋大型导航浮标的基本特点和我国第一座海洋大型导航浮标研制和运用情况,首先分析了大型导航浮标的运动特性和运动方程,提出摇摆惯性力和升沉惯性力计算分析方法。用全链悬链线方程分析浮标的锚泊系统和单点系泊浮标系统锚链计算方法。其次分析了全天候抗冰浮标的结构型式以及海冰对浮标的作用力,重点分析大面积冰排和漂流冰对浮标的作用力。最后给出TJ-1号海洋大型导航浮标的主尺度、性能参数、导航设备和使用情况。
According to the basic features of marine large navigation buoys and the research and application of the first large marine navigation buoys in China, the kinematics and equations of motion of the large navigation buoys are analyzed first, and the calculation methods of rocking inertia and heave inertia are proposed. Analysis of mooring system of mooring buoys and calculation of mooring chains of single point mooring buoy system based on full chain catenary equation. Secondly, the structure type of the all-weather anti-ice buoy and the force of sea ice on the buoy are analyzed. The force acting on the buoy by the large-area ice-rafting and drifting ice is analyzed emphatically. Finally, the main scale, performance parameters, navigation equipment and usage of TJ-1 marine navigation buoy are given.
