A modal-based derivation of transient pressure distribution along the tyre-road contact
journal contribution
posted on 2013-01-10, 10:01 authored by Achillefs Tsotras, Georgios MavrosGeorgios MavrosThe two-dimensional, frictional tyre-road contact interaction
is investigated. A transient contact algorithm
is developed, consisting of an analytical belt
model, a non linear sidewall structure and a discretized
viscoelastic tread foundation. The relationship
between the magnitude/shape of the predicted
two-dimensional pressure distribution and the corresponding
belt deformation is identified. The effect of
vertical load and the role of sidewall non linearity are
highlighted. The modal expansion/reduction method
is proposed for the increase of the computational efficiency
and the effect of the degree of reduction on
the simulation accuracy is presented. The qualitative
results are physically explained through the participation
of certain modes in the equilibrium solution, offering
directions for the application of the modal reduction
method in shear force oriented tyre models.
