Our modeling interface capabilityDynamic – Rail System Simulation (D-RSS)D-RSS
Our in-house dynamic interface modelling tool validated to EN 50318:2018 and tested in several OCS and pantograph systems across the world. Incredible results are enabled by direct insights of the as-fitted infrastructure, such as implementing the as-build infrastructure geometry and the in-depth knowledge of pantograph hysteresis and aerodynamic effects to the interface performance.
Dynamic – Rail System Simulation (D-RSS) is the in-house Overhead Contact System (OCS) to Pantograph interface capability of T-RIS. D-RSS development began in 2017 with the objective to:
- closely match instrumented pantograph test forces with the modelling output under diverse operational conditions and bespoke design parameters
- capture the design to site transition of the infrastructure geometry due to installation, design and manufacturing tolerances
- create high-accuracy OCS digital twins that can easily implement high-volume OCS production design into interface models, while maintain an easy design interface to enable bespoke components to be easily incorporated
Validation
D-RSS is validated to fulfil the EN 50318:2018 and third party certification is currently ongoing with the Network Rail Certification Body (NCB) in the UK. Contact us for more details.
The pantographs
A variety of pantographs in lumped mass model and multi-body configurations are already implemented in the D-RSS library. Contact us for more details.
Pantograph aerodynamics and hysteretic response modelling
The standard lumped mass models often used by interface modelling simulation packages satisfy a limited range of the actual operation scenarios often encountered during the actual pantograph life cycle. These parameters are:
- intrinsic to the pantograph design, such as the hysteretic pantograph bevaviour
- rolling stock specific, such as the knuckle travelling orientation, relative distance to adjacent pantograph in multiple unit operation and position on the train formation
- miscellaneous due to weather conditions
Through extensive research and data analysis from multiple sources from T-RIS and the collaboration with academic partners a systematic approach has been tested and used in a number of R&D and industrial projects.
