"Steady Motion of a Slack Belt Drive: Dynamics of a Beam in Frictional Contact With Rotating Pulleys";
Journal of Applied Mechanics - Transactions of the ASME, 87 (2020), S. 1 - 12.

We seek the steady-state motion of a slack two-pulley belt drive with the belt modeled as an
elastic, shear-deformable rod. Dynamic effects and gravity induce significant transverse
deflections due to the low pre-tension. In analogy to the belt-creep theory, it is assumed
that each contact region between the belt and one of the pulleys consists of a single sticking
and a single sliding zone. Based on the governing equations of the rod theory, we for the
first time derive the corresponding boundary value problem and integrate it numerically.
Furthermore, a novel mixed Eulerian-Lagrangian finite element scheme is developed
that iteratively seeks the steady-state solution. Finite element solutions are validated
against semi-analytic results obtained by numerical integration of the boundary value
problem. Parameter studies are conducted to examine solution dependence on the stiffness
coefficients and the belt pre-tension.
