Forms and criteria of assessment
Entry Knowledge
Railway superstructure and modern railway structure design, the interaction between railway vehicle and track, static track design, switches, crossings and turnouts.
Basic principles of numerical computations, basic elementary problems of numerical mathematics.
Physics, vibrations, proper vibrations, the energy of harmonics vibrations, damped vibrations, forced vibrations, the addition of vibrations
Examination of the response of structures subjected to excitation, bases of the vibration theory, frequency domain analysis.
Aims
The aim of the course is to familiarize students with the issues of dynamic analysis of railway track construction, measuring techniques and methods of modelling the track bed. Another aim is to familiarize students with the issues of noise and vibration, including the design of measures against these phenomena. Students will also become familiar with the basic principles, functions and practical use of intelligent sensor systems in modern construction. This area also includes methods of evaluating measured data using basic and advanced methods in the time, frequency and time-frequency plane, including selected machine learning methods.
