摘　　要：应用通用有限元软件Ansys10.0,建立了海洋钻井平台隔水套管对中装置的三维弹塑性非线性接触问题的有限元力学分析模型,对其结构强度及变形进行了分析。分析得到结构中最大等效应力出现在门轴处,大小为273MPa,小于材料的屈服应力,结构变形情况也与实际工作情况一致。对复杂结构内部的应力与变形进行有限元分析,为结构设计的优化与改进提供了依据。By means of ANSYS large-scale universal finite-element software,the finite element analysis model of non-linear contact of 3-D elastic-plastic feature of the ocean casing pipes centering device. The maximum stress of the structure appears near the doorpost,it＇s value is 273Mpa which is less than the material bending intensity,so it met the require of the work condition. It＇s deformation is also accordence with the real work condition, conforming the design requirement. Obviously the FEM analysis of the complicated structure provides basis for the improving of the structure design.
