摘要
针对双鞍座卧式容器,在建立了鞍座真实结构模型基础上,在鞍座与筒体之间分别采用全焊接和全接触支承方式条件下,进行了有限元模拟计算,得到了鞍座处筒体上的应力分布,并对计算结果进行了对比分析。计算结果表明,连接方式的不同,筒体上最大等效应力的位置与大小均不一样,并且鞍座处筒体的应力分布也不相同。计算结果对于鞍座与卧式容器连接方式的选择提供了依据。
In the actual manufacturing process of horizontal vessel, saddle majority connected with cylinder by welding, but sometimes loose fitting also used. In this paper, a reasonable form of the saddle has been chosen according to the diameter of the cylinder, established the true saddle finite element model and get the stress distribution and size of cylinder near saddle. The results have been compared by analyze. In contact model, the role of the static friction between cylinder and saddle, so establish contact pairs between the saddle and cylinder surface and the use of finite element method to contact analysis.
