摘要
以导管架平台相似模型为例,应用ANSYS软件建立平台的有限元模型,通过逐级施加环境载荷的方法,对平台结构的均匀腐蚀、杆件弯曲两种情况做了极限承载力的非线性分析,得出结论:不同方向的载荷对平台承载力产生的作用不同,沿x轴方向极限载荷大于沿y轴方向极限载荷,杆件均匀腐蚀损伤平台的极限承载力要低于杆件弯曲损伤平台的极限承载力。
Similar model as an example to jacket platform, finite element model of ANSYS software to establish a platform, by applying the environmental load step by step, the uniform corrosion of platform structure, bar bending ultimate bearing capacity of nonlinear analysis has been done for the two cases, come to the conclusion that, differently in the direction of load bearing capacity of platform is different, along x axis direction limit load is greater than the limit load along y direction, the ultimate bearing capacity of the bar uniform corrosion damage platform is lower than the ultimate bearing capacity of the bar bending damage platform.
