中文摘要:
      钢构支架是半潜式钻井平台管道支吊架的主要类型之一,钢构支架的极限强度是管道系统正常工作的重要保障。研究结构极限强度的方法有理论分析、有限元数值仿真和实验分析。在分析极限理论的基础上由静力法计算四种钢构支架试件的极限载荷;利用MSC软件对试件极限载荷进行数值仿真分析,并对有限元模型化技术进行讨论;对试件进行实验极限载荷测试,对比分析了三种方法测得的极限载荷。结果表明,三种分析方法计算得到结构的极限载荷基本一致,对于结构形式较为简单的结构通过理论分析可以得到简化解析
英文摘要:
      Structural support is one of main type of pipe supports used in semi-submersible drilling platform. Ultimate strength of structural support is the most important factor for normally working of pipe system. Three methods, including theoretical analysis, finite element analysis and experimental analysis were used for analysis the limit load of structural supports. First, mechanical models were established and theoretical limit loads of four structural supports (cantilever support and portal support both for angle steel and H steel) were calculated out by static method. Four finite element models were built by using the software of MSC.Patran. Load-displacement curve was figured out and the limit load was determined by four criterions. At last, Experimental of limit load was carried out. The comparison between experimental results and numerical results by different finite element models were also discussed. Results show that the theoretical analysis is usually used for simple structures and the precision of method is affected by mechanical model. The reasonable finite element model such as structural model, load and boundary condition are key factors for numerical simulation.
