FSD3310 Wheel-Rail Contact 6.0 credits

Introduction to rolling contact phenomena, overview of different contact theories, the normal contact problem – Hertz’ theory, linear and non-linear theories for the tangential contact problem, wheel-rail contact in vehicle dynamics simulation software, contact geometry, deterioration mechanisms, influence of lubrication, non-stationary contact mechanics and the development of corrugation.

The course aims at the understanding of the conditions in the wheel-rail interface with phenomena related to the rolling contact. Theoretical background and approaches to numerical solution in the context of dynamic simulations are addressed. The course contains lectures, seminars where the students present a selected topic, and home assignments.

Undergraduate courses in mechanics, solid mechanics, and multibody dynamics.

Undergraduate courses in mechanics, solid mechanics, and multibody dynamics.

If the course is discontinued, students may request to be examined during the following two academic years.

• INLA - Assignment, 6.0 credits, grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Compulsory lectures, seminar with presentation of a selected topic, home assignments.
