A New Simple Belt Friction Model

Frydrýšek K., Hrabovský L., Čepica D.
pages 49 - 52, full text

Article focuses on the belt friction which obeys Coulomb’s Law. It presents a new model, which is compared to the traditional simple Euler-Eytelwein (Capstan) model. Derivations are based on the differential equilibrium of forces in a cylindrical coordinate system on an elementary segment of a rope. Compared to the Euler-Eytelwein model, our new model additionally respects the weight of the rope, the radius of the cylindrical surface, the rope’s geometry, and the rope’s position relative to gravitational force in space. Experiment using a pulley with a semicircular groove wrapped with a loaded rope and the measuring of the forces in the rope was used to evaluate it. Our new model is slightly more complicated and precise than the Euler-Eytelwein model. Finite Element Method is applied too.
