Clutches

Description

The model consists of a series of coupled inertia components separated by clutches between them. When a clutch is engaged, friction will be present between two adjacent inertia components, causing them to transfer momentum to each other. The first and the last inertia components are damped by rotational dampers, and a constant torque is applied to the first inertia.

From left to right, the first two clutches are timed so that they disengage after 15 seconds and engage after 5 seconds, respectively. The third clutch can be controlled by user input. On the top level, that user input is also connected to a timer, engaging the clutch after 10 seconds.
