Mechanical Rotational System with Stick-Slip Motion

This model demonstrates a mechanical rotational system, where a load consisting of a spring, inertia, and viscous rotational friction is driven by a velocity source in such a way that velocity is constant from 2 to 3 s and from 5 to 6 s. The friction element is installed between the load and the source, and there is a difference between the breakaway and the Coulomb frictions. As a result, stick-slip motion is developed in the regions of constant velocities.
