摘要
研究了变电构架中钢管刚性法兰盘连接的抗拉受力性能,应用大型有限元软件ANSYS进行了非线性数值分析,揭示了刚性法兰盘在拉弯力作用下的受力特点,将有限元计算结果与《架空送电线路杆塔结构设计技术规定》(DL/T5154-2002)计算结果进行对比分析,为修编《架空送电线路杆塔结构设计技术规定》刚性法兰节点连接章节提供参考依据。
The function of flange joint with stiffening rib in powertransformed frames under tension is studiedAnd an nonlinear finite element analysis is conducted,by generalpurpose finite program ANSYSThe results show the characteristic of the flange with stiffening rib under tension and bendingThese results are compared with those of “Technical Regulation of Design for Towers and Pole Structure of Overhead Transmission Line”(DL/T 51542002) and be referential to mending the pertinent clauses of the code
