摘要
变压吸附塔长期承受交变载荷,主要失效模式为疲劳失效。本文介绍变压吸附塔的结构及其应力分析,针对椭圆形封头及球形封头开孔处应力分布,提出变压吸附塔封头结构形式的优化。
The pressure-swing absorber was often suffered from alternating load,resulting mainly in fatigue failure.This paper introduced the structure of pressure-swing absorber and its stress analysis.Regarding to the stress distribution on the opening of ellipsoidal head and spherical head,the improvement method on the head structure of pressure-swing absorber was presented.
