- 摘要:
- 采用ABAQUS大型非线性有限元软件,对15万m3双盘式浮顶原油储罐的应力进行了分析,计算出储罐的应力分布,并根据压力容器设计标准,对储罐的应力分布进行了评定。分析表明,储罐在储存原油时是安全的。除最上层和最下层外,储罐壁板的应力分布均匀,并且都保持在一个较高的水平。储罐壁板最大应力位置在下面的第2层罐壁上。储罐底板应力比较低,但边缘底板与壁板焊接部位的内侧应力很高,应力值超过材料的许用应力,但将应力分类后,应力能够满足相关法规要求。
A 15×104 m4 crude oil tank was analyzed by the famous nonlinear finite element software ABAQUS.The stress distribution of the whole tank was calculated and the stress distribution was evaluated based on the design standard of pressure vessel.The analysis shows that the tank is safe for storing crude oil.The stresses in tank wall, except the upper and lower parts of the wall,are at uniformly high level.The highest stress locates at the lower second layer of the wall.The stresses in bottom plates are low.But the stresses at welding inner corner between wall and bottom are higher than the permitted stress of the material.However,by classifying the stresses,they satisfy the relevant standard requirement.2008,1(1): 17-20 收稿日期：2007-3-19分类号：TE972作者简介：盛选禹(1969-),男,山东定陶人,1998年博士毕业,副研究员,主要从事反应堆结构设计、结构强度分析、摩擦学研究工作,发表论文70余篇,专著8部.参考文献：
