摘　　要：运用ANSYS软件建立球罐参数化模型,研究球罐整体在实际工况以及外力极限组合工况载荷作用下的应力和位移状态以及其分布规律,分析球罐的最大应力节点和具体危险部位,提取危险路径进行线性化处理,对球罐应力强度进行安定性分析。根据计算结果进行预测和诊断出最容易导致乙烯球罐裂纹的位置和原因,为项目的本质安全设计提供参考。This paper uses ANSYS software to establish the model of the spherical tank, analyzes its stress distribution and displace- ment state under the conventional load and ultimate load, its maximum stress node and specific dangerous position and puts forward a linearized method for the dangerous parts with the fillet weld, which can be used to analyze the stress intensity stability. According to the calculation result, it is easy to predict and diagnose the cracking cause and location of the ethylene spherical tank.
