Description

This models represents a belt and pulley. The connection to the pulley is through the rotation port p_rot. The connection to the belt is through the translation port p_trans. The model is ideal, i.e. there are no compliances or inertias. The causality of this model is always mixed: torque out & velocity out or angular velocity out & force out:

 

p_rot.T = radius * p_trans.F

p_trans.v = radius * p_rot.omega

 

or:

 

p_trans.F = 1/radius * p_rot.T

p_rot.omega = 1/radius * p_trans.v
