摘要
综合科考船布设有大量科考设备,如何合理地设计相关设备的基座结构加强,在确保设备正常使用的同时有效控制结构重量,是科考船结构设计的重要课题之一。而动载荷系数的选取则直接决定设计载荷的大小,是加强设计的先决性条件。目前,船级社相关规范公式系针对海上常规起重设备,无法根据设备相对船体位置具体考虑每个科考设备的动载荷系数。另外,从安全角度考虑,宜对设备商所提供建议值进行验证/检验。所以有必要通过直接计算方法,综合考虑船舶的实际作业航速和海况,以及各类科考设备实际使用情况,以合理确定设备加强的动载荷系数,为实船设计提供依据。
Due to diversity of research equipment onboard of multidisciplinary research vessel, it is important to design the foundation reinforcement properly to make sure the related equipment work normally, and control the hull weight at the same time. Since the selection of dynamic load factor directly affects the design load, it is the prerequisite of reinforcement design. The class society’s rule formulas doesn’t consider the dynamic load factor of a specific equipment, which cause it’s impossible to take the actual operation situation into account. Thus, the operation speed and sea state should be considered through direct calculation in order to determine the dynamic load factor reasonably.
