摘要: 球罐作为储存和运输的压力容器,广泛应用于化工、石油等领域,在其加工使用过程中,容易出现裂纹等缺陷,导致安全隐患。通过ANSYS软件对一出现穿透裂纹的Q370R球形储罐进行有限元分析,应用J积分理论并采用通用失效评定图方法对缺陷进行评估。该方法可为含缺陷压力容器安全评价提供参考。

关键词: 球罐, 穿透裂纹, 缺陷评定, J积分, 失效评估图

Abstract: As the storage and transportation pressure vessel, spherical tank is widely used in chemical engineering, petroleum and other fields. In the process of manufacture and usage, defects such as cracks can easily appear, which will results in safety risks. In this paper, the finite element analysis is carried out on a Q370R steel spherical tank with penetrated crack by adopting ANSYS software, and the defect is evaluated by applying the general failure assessment diagram based on J-integral theory. This method can provide a reference for the safety evaluation of pressure vessels with defects.

Key words: spherical tank, the penetrated crack, defect assessment, J-integral, failure assessment diagram
