石油套管在进行结构设计的时候,如果还在沿用传统的方法对石油套管进行结构的设计,他的一些部位重要的影响因素不容易考虑的到。从而通过最后所得出的安全系数以及应力和变形的误差相对来说比较大,会使得它的安全系数变得比较低,本文主要通过Cae数值反正方法对石油套管的最大屈服强度和结构设计进行了优化的讨论,从而选择最佳的设计方案,希望本文的论述,能为以后的具体工作,起到一定的参考作用。
Oil casing In the structural design, if the traditional method is still used to design the structure of the oil casing, some of his important influence factors are not easy to consider. So that the safety factor obtained through the final and the relatively large error of the stress and deformation will make its safety factor become relatively low. In this paper, the maximum yield strength and structural design of the oil casing are mainly carried out by the Cae numerical method Optimized discussion, so as to select the best design, I hope this article’s discussion, for future specific work, play a certain reference.
