散粮皮带通廊结构静态性能分析

摘要

Belt corridor is a major bulk terminal equipment.Due to its long design life,bulky structure,maintenance complexity,especially harsh seaside working conditions,the corridor’s steel structure is susceptible to corrosion damage, which severely reduces the safety and reliability of the gallery structure.Taking bulk grain belt corridor device in Tianjin Harbour Second Stevedoring Co.,Ltd as the research subject,a finite element analysis model was established according to characteristics of the structure and condition of such equipment and in accordance with design drawings and actual corrosion damages.An in-depth study of the static performance of belt corridor structure was carried out,whichprovides a theoretical basis for the maintenance management scheme.%皮带通廊是散货码头的主要设备之一，由于该类设备的设计寿命较长，结构体积较大，维护节点多，特别是长期处在海边恶劣的工况条件下，其钢结构容易发生锈蚀损伤，严重降低了通廊结构及整套设施的安全可靠性。以天津港第二港埠有限公司散粮皮带通廊设备作为研究对象，根据该类设备的结构及工况特点，并依据设计图纸及实际锈蚀损伤情况，建立有限元分析模型，深入研究了皮带通廊结构的静态性能，为皮带通廊的维护方案提供了理论依据。
