Distributed Numerical Calculations of Wear in the Wheel-Rail Contact
Preprints aus dem Fachbereich Mathematik, Universität Rostock
Abstract: We study numerical aspects of wear problems
- 65C20 Models, numerical methods
- 73T05 Contact and surface mechanics
in railway mechanics.
A short overview of the needed components -- a dynamical
vehicle/track model, contact geometry and contact mechanics --
is given to demonstrate the complexity of the problem.
An algorithm for the integration of the domain evolution equation
describing wear in the long time scale is presented and discussed.
Solutions for simple choices of the model components are studied.
Finally, ways to couple the most advanced available models via
internet programming are demonstrated on the basis of a vehicle model
due to Meinke in a co-simulation with our own geometry program.
Keywords: railway mechanics, contact mechanics, wear problems, domain evolution, numerical co-simulation
