摘　　要：带缆桩和导缆孔在船舶系泊、拖带作业中通常会受到很大的载荷作用,在船舶设计过程中有必要对系泊、拖带设备的支撑结构进行强度分析。以MSC.PATRAN/NASTRAN为平台,根据船体尾部甲板的结构形式、系泊和拖带设备布置以及船体结构加强形式建立船体局部有限元模型,通过对不同设计方案下的支撑结构进行计算,分析比较导缆孔、带缆桩区域船体加强结构的应力分布情况,并着重对导缆孔区域的加强形式进予以考虑,以期为系泊、拖带设备加强结构的强度校核和优化设计提供一定的参考。Bollard and chock are usually affected by large loads in the mooring or towing operations. It is necessary to analyse the strength of reinforcements of mooring and towing equipment. Based on the MSC.Patran/Nastran, the local hull finite element models were established according to the aft deck grillage arrangement, mooring and towing equipment arrangement and the type of reinforcements. According to the calculation of reinforcements under different design plans, the different stress distribution of the reinforcements were ana-lyzed and compared. The types of reinforcements of chock were primarily took into consideration. This research will provide certain reference for the checking and optimization of reinforcements of mooring and towing equip-ment.
