A Full-Vehicle Motion Simulator for Railways Applications

The present study attempts to develop a 3D multi-body dynamic model of a train. First, a software is developed to simulate the longitudinal dynamics of the train by treating the train body as a point mass moving on a track. It has applications in railway operations like runtime estimation, trajectory calculation, and route planning. Additionally, a 3D dynamic model of the train was built to gain insights into the motion of train components in response to forces arising from wheel-rail interaction and external track inputs. Finally, a method is proposed to realistically capture the motion of an N-compartment train as it traverses along the entire journey, for a typical route used by the trains in India.
