裙座与塔式容器不同连接型式的对比分析

COMPARATIVE ANALYSIS OF DIFFERENT CONNECTION JOINTS BETWEEN SKIRT AND TOWER

随着石油化工设备向大型化和轻量化方向发展,塔式容器的操作工况也越来越复杂.在不同类型载荷的作用下,裙座与塔体连接处的应力分布各有不同,设计中如何正确地选取连接型式成为设计人比较关注的问题.文章采用有限元方法对裙座与塔式容器的不同连接型式展开了研究,探讨其在不同载荷下的应力分布和变形特点,同时考察了不同对齐方式对连接处的影响,为裙座支撑容器的设计提供参考.

With the development of petrochemical equipment towards large scale and lightweight,the operating conditions of towers are becoming more and more complicated.The stress distribution is different at the connection between the skirt and the bottom of the tower under different types of loads.Therefore,how to choose the connection type correctly in the design has become the main concern for designers.In this paper,the finite element method is adopted to study the different connection types between the skirt and the tower,explore the characteristics of stress distribution and displacement under different types of loads and investigate the effects of different alignment to the connection.This provides reference for the design of vessels with skirt support.
