科考船雷达桅杆减振设计

Vibration Reduction Resign of Radar Mast of Research Vessel

为防止雷达桅杆振动过大影响雷达桅杆上设备的正常使用,对其进行减振设计。采用有限元方法对某科考船的雷达桅结构进行有限元建模和详细的振动特性分析,在此基础上开展减振设计,使雷达桅杆的振动大幅下降。提出的计算设计方法和所得结果对此类船型的雷达桅杆设计具有重要的参考价值。

In order to prevent the excessive vibration of the radar mast from affecting the normal use of the equipment on the radar mast, the vibration reduction design is carried out. The finite element modeling and detailed vibration characteristics analysis of radar mast structure of a scientific research ship are carried out by using the finite element method. On this basis, the vibration reduction design is carried out, and the vibration of radar mast is greatly reduced. The proposed calculation design method and the obtained results have important reference value for the radar mast design of this type of ship.
