A MODEL FOR THE DYNAMIC ANALYSIS OF A BELT TRANSMISSION USING THE DAHL FRICTION MODEL

摘要

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.
