In order to realize the intelligent analysis of longitudinal force and deformation of CRTSⅡ slab 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 CRTSⅡ slab 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 typeⅡ slab ballastless track CWR on bridges.
