摘　　要：桁架式桅杆是船舶上的重要结构,其结构强度及稳定性直接关系着船舶的安全问题。基于中国船级社相关规范,利用有限元分析软件MSC.Patran/Nastran对某钢质综合试验船的桁架式桅杆进行了不同载荷工况下的强度及稳定性分析和评估,结果表明该桁架式桅杆结构安全可靠。文中采用的校核方法可为其它类似桅杆结构强度及稳定性有限元分析提供一定的参考。Truss type mast is the main structure of a ship, the structure strength and stability of it is related to the security of a ship. The analysis and assessment of structural strength and stability under different loads of truss type mast in a steel sea-going test ship is carried out by the finite element analysis software MSC.Patran/Nastran based on the CCS rules. The results indicate that the structure of the truss type mast is safe and reliable.
