Optimizing Railway Dynamics Using Digital Twins
The interest of dynamics simulations in this sector.
Quandyga Engineering supports railway stakeholders in analyzing and optimizing the dynamic behavior of vehicles, tracks, and associated systems.
Our physics-based digital twins allow for detailed modeling of wheel-rail interactions, vehicle dynamics, and complex systems to improve performance, safety, and sustainability.
The challenges of this sector:
The railway industry imposes high demands in terms of stability, safety, comfort, and maintenance. A detailed understanding of dynamic phenomena is essential, including:
Ensuring operational safety
Controlling wheel-rail wear
Optimizing suspensions and embedded systems
Reducing maintenance costs
Facilitating certification
Maximizing the lifespan of components
Thanks to our expertise in multibody simulation with Robotran and the coupling with other physical modeling (pneumatic for suspensions, granular for ballast, electric for actuators, etc.), we develop models tailored to each project.
