With over 30 years of experience in designing, manufacturing and maintaining on-board communication and control systems, Televic Rail is a leading, trusted partner for railway operators and train builders worldwide.
Our Passenger Information Systems and Control Systems are high quality, tailor-made solutions that offer the flexibility, user-friendliness and stability that our clients ask for. 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.
In order to predict bogie instabilities due to extreme speed profile, short track radii, lateral gust winds etc., we have developed an instability monitoring system (IMS) that can trigger a safety line when such instability is crossed.
This IMS system will continuously look for acceleration oscillations, and trigger an instability flag when the oscillations count goes above a given threshold. This instability threshold is given by the train builder and purely based on experimentation.
The goal of this topic is to make use of an inhouse multi-body bogie model to be able to find out the instability threshold in function of the bogie stiffness, dampening ratios, mass distribution and geometries. The student will have to perform a parametric study in order to express the instability threshold.
