Rail infrastructure modelling
LUSAS provides a comprehensive range of facilities to let you model all sorts of rail infrastructure .
Rail infrastructure capabilities
Rail load optimisation
- Generate the most critical rail loading pattern for a selected track layout, for each influence shape under consideration.
- Watch this short video to see how to carry out a train/rail load optimisation analysis on a two-span box beam bridge that is modelled using shell elements. (Version 18.0)
High Speed Rail dynamics
- Automated approach to rail vehicle dynamics.
- Includes load and sprung-mass interaction approach to vehicle modelling.
- Applicable to simple and advanced structures.
- Rapid solution times and flexible detailed reporting.
Rail Track-Structure Interaction
- Parametric approach to track, structure and load modelling.
- Creates models in SI or US units in accordance with codes .including UIC 774-3 and guidelines of various Eurocode national annexes.
- Includes checks for vehicle acceleration and braking, temperature.
- Detailed standardised results reporting.
Soil-Structure Interaction
- Soil and structure modelling in one software package.
- Applicable to any bridge and tunnelling SSI problem.
- Available in both 2D and 3D and incorporating time phases.
- Models soil phenomena including stability, sliding, consolidation, seepage and dynamics.
Detailed Rail Bridge Assessment
- Detailed modelling of rail structures for linear and nonlinear assessment procedures.
- Local and global, linear and non linear buckling capability.
- Advanced analysis capabilities can help derive increases in assessed capacity and thus reduce cost of remedial works.
Rail Break Analysis
- Detailed modelling of rail, fasteners, superstructure and structure
- Gap control calculation following break
