| 摘 要： | 首先采用简化的理论计算方法计算了井口装置阀体的等效应力，然后采用有限元分析技术对该型阀体的应力应变大小及分布进行了数值计算。将两种方法进行比较，说明理论简化计算有较大误差，提出了理论计算的修正办法。

| Abstract: | A simplified theoretical method is used first to calculate the equivalent stress on wellhead valve bodies, and then a finite element analytical technique is applied to numerically calculate the size and distribution of stress and strain, a comparison is made between the 2 methods, it shows that there exist big errors in the simplified method, thus a method for revising the theoretical calculation is put forward. |
