法兰紧固连接系统正向设计规范研究
Research on the Forward Design Standards for Fastening and Connecting Systems of Flanges
摘要
Abstract
To address the limitations of flanges with bolted joints systems in the preliminary selection,layout optimization,response analysis,and safety assessment,a forward design method oriented to high performance and complex service conditions is proposed.Design criteria and an optimization method for the layout of bolted joints are established.Based on the load extraction technique,a high-accuracy mechanical model for the load-bearing behavior of a single bolted joint is developed.An improved safety standard for the stress and strength verification of a high-strength bolted joint is proposed and a complete and efficient forward design system is established.The proposed method is validated through numerical examples.The results demonstrate that the developed forward design framework can effectively avoid over-design and under-design,enabling a full-process forward design of flange bolted joint systems from preliminary configuration design and local load-bearing verification to overall reliability assessment.关键词
