【摘要】 通过有限元直接计算,对不同载重量散货船要求采用不同结构形式从理论上进行了一定分析说明。具体针对双层底板架,底边水舱,以及底墩下纵桁等结构进行分析,找出热点应力所在之处,并根据热点应力形成原因,得出结构形式上的应对方法。更多还原

【Abstract】 Structure strength requirements are analyzed for different deadweight cargo bulk carriers.The investigation focus on the double bottom frames,slop plates of hopper tanks and the longitudinals under the lower stool in way of transverse bulkhead.The results are obtained from direct calculation of the Finite Element Method.The locations of hotspots are found for different structures.Finally,the settlements are proposed for each hotspot.更多还原
