摘　　要：H型加强圈因可显著提高圆筒的临界失稳压力而在真空容器中应用广泛,但基于GB 150-2011标准进行设计需要经过反复试算,流程繁琐。本文推导了圆筒形真空容器H型加强圈的简化设计计算公式,并通过建立数值计算模型验证了简化公式的准确性,最后通过对设计计算算例进行分析,研究了H型加强圈结构参数设计及其对圆筒形真空容器稳定性和经济性的影响。结果表明:本文推导的H型加强圈简化设计计算公式可在满足结构稳定性要求的前提下,一次性通过设计曲线快速对H型加强圈进行设计和校核;增大H型加强圈的高度和厚度可提高圆筒的临界失稳压力;与矩形加强圈相比,采用H型加强圈可降低材料的用量,提高经济效益。研究成果可用于指导圆筒形真空容器H型加强圈设计计算并为结构完整性评价提供理论参考。H-type reinforcing ring is widely used in vacuum vessel because of significant improvement of the critical instability pressure of the cylinder.However,the design based on GB 150-2011 standard requires repeated trial calculations and the process is cumbersome.In this paper,the simplified design calculation formula of H-type reinforcing ring for cylindrical vacuum vessel was deduced,and the accuracy of the simplified formula was verified by establishing a numerical calculation model.Finally,through the analysis of the design calculation example,the selection design of the structural parameters of H-type reinforcing ring and its influence on the stability and economy of cylindrical vacuum vessel were studied.The results show that the simplified design calculation formula of H-type reinforcing ring deduced in this paper could meet the requirements of structural stability,and the design and check of H-type reinforcing ring could be carried out quickly by the design curve at a time.Increasing the height and thickness of H-type reinforcing ring could improve the critical instability pressure of the cylinder.Compared with rectangular reinforcing ring,the use of H-type reinforcing ring could reduce the amount of material and improve the economic benefits.The research results can be used to guide the design and calculation of H-type reinforcing ring of cylindrical vacuum vessel and provide theoretical reference for structural integrity evaluation.
