Intelligent Analysis System for Longitudinal Force of CRTSⅡSlab Ballastless Track on Bridge

为实现桥上Ⅱ型板式无砟轨道无缝线路纵向受力与变形分析的智能化,考虑了桥梁结构、轨道板以及钢轨之间的相互作用,利用有限元法建立了多跨简支梁和大跨度连续梁桥上CRTSⅡ型板式无砟轨道无缝线路精细化有限元模型;采用C#语言对ANSYS进行二次开发,研发了集参数输入、有限元建模、荷载施加、自动计算、数据提取及数据智能处理于一体的纵向力智能分析系统。通过与已有文献对比,验证了智能分析系统的通用性和可靠性,可为桥上Ⅱ型板式无砟轨道无缝线路的设计提供参考。

In order to realize the intelligent analysis of longitudinal force and deformation of CRTSⅡslab ballastless track CWR on bridge,this study considers the interaction between bridge structure,track slab and rail,and establishes a refined finite element model of CRTSⅡslab ballastless track CWR on multi-span simply supported beam and long-span continuous beam bridge by using finite element method.The re-development of ANSYS is carried out by using C#language.An intelligent analysis system of longitudinal force is developed,which integrates parameter inputting,finite element modeling,loading application,automatic calculation,data extraction and intelligent data processing.The analysis system′s universality and reliability are confirmed through a comparison with previous research findings.The analysis system can provide reference for the design,operation and maintenance of typeⅡslab ballastless track CWR on bridges.
