桥上无缝道岔智能化分析系统研发
Development of an Intelligent Analysis System for Seamless Turnouts on Bridges
摘要
Abstract
Compared with continuous welded rail on bridges,the mechanical behavior of seamless turnouts on bridges is more complex,and specialized calculations are required for each seamless turnout at every elevated station during the design phase.To address issues of complex calculation models,numerous parameters,and significant theoretical challenges for seamless turnouts at elevated stations,a calculation system for seamless turnouts on bridges with completely independent intellectual property rights was developed.This system was based on the turnout-bridge-pier interaction mechanism,utilized C# for interface development,and adopted a finite element secondary development language for kernel programming.Compared with existing software,the developed seamless turnout system featured the following innovations.It enabled'one-click input'of multi-disciplinary data for railway,bridge,and tunnel engineering,dynamic visualization of design parameters,'one-click modeling'and'one-click calculation'of highly nonlinear coupled models for seamless turnouts in large marshalling stations,and'one-click output'of intelligent analysis results,parameter verification,and calculation reports for seamless turnouts on bridges.Taking a group of seamless turnouts at an elevated station on the Nanchang-Jiujiang High-speed Railway as an engineering case,this study introduced the application of the system in parameter input,model establishment,result analysis,and other aspects.The system has already been applied to the design of seamless turnouts on bridges in multiple projects,and the calculation time for groups of seamless turnouts on bridges at complex bridge sites can be controlled within 1 hour.关键词
