Design Method and Fatigue Analysis of Rectangular Vessel Door Structure
Rectangular vessel is a special type of structure in pressure vessels,and their door structure,as one of the important components in rectangular vessel,can be designed and calculated using the rule design method.Due to the particularity of their structure,design by analysis methods can also be used.This article conducts rule design and analysis design on the door structure and compares the two calculation methods.At the same time,fatigue analysis was conducted on the door structure,and it was found that the door structure has an infinite fatigue life,meeting the fatigue design requirements.
