Our various types of on-board control systems such as our bogie monitoring systems are innovative yet reliable products which are designed specifically for the railway business.
Trains and trams all around the world are equipped with Televic Rail solutions, from New Zealand to Canada, from China to the United States, from India to Belgium, England and France.
More and more kinematic and structural modelling is needed in order to support mechatronics system architecture and design validation. The use of simulation tools supporting this activity is imposing itself because of complexity.
The subject of this topic is to derive an initial 3D multi-physical model of a bogie. This simulation tool will bring insight w.r.t the effect that certain defects have on the on the vibration signature of the train bogie parts. Such defects can be for instance related to roundness issues, track problems, track parallelism.
Although the model will be purely mechanical, an emphasis will be put on the multi-physical aspect of it. This would allow us to add more complexity to the model in the future (not in the scope of this topic), such as thermal, chemical, electrical etc..
The goal of the student will be organized as follow:
Literature study on bogie multi-physical modelling
Implementation of a simple 1D model
Implementation of the 3D model
Calibration of the 3D model throughout real datasets
Simulation of specific scenarios (wheel flat, bogie hunting, track grove)
Physics (basics of mechanics, conservative law of mass, energy and momentum...)
Basis of simulation (notion of causality, numerical simulation ..)
Differential calculus and integral
Programming language and Modelling software (Matlab and/or 20sim and/or Modelica)
