摘要:
为了研究聚乙烯（PE）管道热熔孔洞缺陷与寿命之间的关系，基于Ansys软件对埋地状态下的含有热熔孔洞缺陷的PE管道进行应力分析，得到了含热熔孔洞缺陷的PE管道在不同内压下的最大Mises应力、环向应力和径向应力的变化数据；依据应力分析数据，使用Matlab编写程序，根据Suleiman双曲本构模型对PE管道进行了寿命预测。研究结果表明：含有热熔孔洞缺陷的PE管道，其最大应力随管道内压的增大而增大，寿命随着管道内压和缺陷体积的增大而减少，含缺陷管道寿命和内压关系可使用双对数函数来进行描述；使用应力分析和寿命预测相结合的方法，可以得到不同缺陷的PE管道寿命-内压关系式。
Abstract:
In order to study the relationship between defect of hot melt hole and life of the polyethylene (PE) pipe, the stress analysis was carried out on the buried PE pipe with the defect of hot melt hole by using Ansys software, and the variation data of the maximum Mises stress, hoop stress and radial stress for the PE pipe with the defect of hot melt hole under different internal pressures were obtained. Based on the data of stress analysis, the life prediction of PE pipe was conducted according to the Suleiman hyperbolic constitutive model through programming with Matlab. The results showed that the maximum stress of PE pipe with the defect of hot melt hole increased with the increase of pipe’s internal pressure, while the life decreased with the increase of pipe’s internal pressure and defect volume, and the relationship between life and internal pressure of the pipe with defect could be described by the double logarithmic function. The relational expression of life and internal pressure of the pipe with different defects could be obtained by using the combined method of stress analysis and life prediction.
