In the field of pressure vessel design, much research has been done to predict the structural behaviour of round nozzles connected to spherical and cylindrical structures. This has been motivated by the fact that the majority of pressure vessels in industry have round bodies, as these are better suited to withstanding pressure. A large demand however also exists for flat-sided pressure vessels with round nozzles, particularly in the air-cooled heat exchanger industry, but there is a lack of research and guidelines on accurately predicting how these structures behave at the nozzle interface. This paper presents a new model that predicts the linearised stresses occurring in these structures in order to gain a better understanding of how they behave.

模拟压力容器中圆形喷嘴到平板界面的结构行为

在压力容器设计领域,已经进行了很多研究来预测连接到球形和圆柱形结构的圆形喷嘴的结构性能。事实是,工业上的大多数压力容器都具有圆形主体,因为它们更适合承受压力。然而,对于带有圆形喷嘴的平面压力容器也存在着巨大的需求,特别是在风冷热交换器行业中,但是对于准确地预测这些结构在喷嘴界面的行为尚缺乏研究和指导。本文介绍了一个新模型,该模型可以预测这些结构中出现的线性应力,以便更好地了解它们的行为。
