基于舰载天线基座开口性能的分析与研究

Performance Analysis and Research Based on the Opening of Carrier Antenna Pedestal

船舶设备因受长期周期载荷作用,易在设备舱口、检修口等开口处产生应力集中,严重破坏设备结构的连续性。当设备随船大摆动振动时,在开口角隅外的应力梯度较高,应力集中现象明显,易造成设备结构薄弱环节的破坏。因此开展船用承载构件开口对于结构设计的影响研究颇为重要。

Due to long cycle loading, stress concentration is prone to occur in marine equipment and manhole. This seriously do harm to the continuity of the equipment structure. When the equipment swings with the hull, there are highly gradient stress outside of the opening corner. Also the existing of the obvious stress concentration will cause the destruction of the equipment structure weak link. So it is quite important to study the impact tructure design of marine bearing openings.
