text: A model to calculate the locally resolved tangential contact forces of the
wheel rail contact with respect to contact kinematics, material and surface properties
as well as temperature is introduced. The elasticity of wheel and rail is modeled
as an elastic layer consisting of point contact elements connected by springs
to each other and to the wheel. Each element has two degrees of freedom in tangential
directions. The resulting total stiffness matrix is reduced to calculate only
the position of the elements in contact. Friction forces as well as contact stiffnesses
are incorporated by a nonlinear force-displacement characteristic, which originates
from a detailed contact model. The contact elements are transported through the
contact zone in discrete time steps. After each time step an equilibrium is calculated.
For all elements, their temperature and its influence on local friction are regarded
by calculating friction power and temperature each time step.
