A model for the dynamic analysis of a belt transmission using the Dahl friction model

Krzysztof Kubas
The paper presents a two-dimensional model of a belt transmission for dynamic analysis.
It is assumed that the belt is modelled by links joined by spring-damping elements with its
rotational and translational stiffness. Normal forces in the contact between the belt and the
pulleys are implemented by assuming its stiffness and damping, whereas friction is modelled
by the Dahl friction model. The calculation results are also presented in two specific cases
of load of the belt transmission.
