外压锥壳上设置加强圈的设计方法探析

Discuss on Design Method of Setting Stiffeners on Conical Shells Subject to External Pressure

本文根据ASME规范对外压圆筒加强圈、外压锥壳大端或小端和圆筒连接处加强圈所需惯性矩的设计原理,推导出在外压锥壳上设置加强圈时所需惯性矩的设计方法,作为一个建议,以供同行专家们分析、讨论。

Based on the principles in the ASME Code for calculating the required inertia moment for the stiffeners on the cylinders subjected to external pressure, and for the stiffeners on the junctions between the cylinder and small and large ends of conical shell both of which are subjected to external pressure, one design method is derived to calculate the required inertia moment of the stiffeners on the conical shell subjected to external pressure. The method is proposed as a reference for discussion by the engineers and experts in the field of pressure vessel design and fabrication.
