Lectures

Goal

1. Deepening of knowledge in different areas of the dynamic behavior of railway vehicles. 2. Become acquainted with advanced methods and tools for the study of the dynamic behavior of railway vehicles. 3. Training for participation in research and development teams on the projects in the field of rail vehicle dynamics.

Outcome

Аftеr completion of the course a PhD student should be able to: 1. Apply advanced computational methods and computer tools in calculation of various parameters of the railway vehicle dynamic behavior. 2. Analyze specific dynamic phenomena for the movement of rail vehicles. 3. Participates in defining the research program of dynamic problems of rail vehicles. 4. participate in the critical evaluation of research results. 5. Participates in drawing conclusions about the quality of the research results. 6. Participate in proposing future research directions of specific dynamic behavior problems of the railway vehicles.

Theoretical teaching

Depending on PhD. thesis field, following subjects will be more or less deeply studied. Non-linear modeling of the rail vehicles dynamic behavior. Multibody simulation tools. Eigenbehavior. Vehicle elastic body vibrations. Statistical methods for description of geometrical deviations of the track. Non-linear contact geometry. Methods for determination of the equivalent conicity. Counterformal and conformal wheel-rail contact. Non-linear wheel-rail contact models. Kalkers contact theories. Stability of motion. Critical speed. Hunting limit-cycle determination using simulation models. Non-linear curving models. Wheel-rail wear assessment criteria. Advanced assessment criteria of the dynamic behavior of rail vehicles: safety against derailment, track shift force, stability, ride characteristic, track loadings, ride comfort. Advanced tools in dynamic test result analysis. Longitudinal train dynamics. Noise sources and noise abatement methods. Interior and outside noise emission.

Practical teaching

Student makes seminar paper from a selected area upon agreement with relevant teacher and mentor of doctoral dissertation.

Attendance requirement

Previous knowledge of the railway vehicles design at the master course level. Previously completed course of the dynamics at the master level.
