裙座与下封头连接处危险截面强度校核方法

Strength Checking Method of Dangerous Section at Connection of Skirt and Lower Head

立式压力容器设备,有设置裙座的结构,目前我国专业标准GB150 《压力容器》没有给出裙座与下封头连接处危险截面强度校核方法。本案依据理论公式并结合应力集中系数,给出这一连接结构的危险截面的强度校核方法,供设计者参考。

Vertical pressure vessel equipment has skirt structure. At present, the professional standard GB150 "PRESSURE VESSEL" does not give the method of checking the strength of dangerous section at the connection between skirt and lower head. Based on the theoretical formula and the stress concentration factor, the strength checking method of the dangerous section of this connection structure is given for Designers’ reference.
