Represent body with rotational inertia
Solver & Inertias
The Inertia block represents a rigid rotating body. It rotates about the connected driveline axis, which carries the degree of freedom of motion. The body carries a rotational moment of inertia about that axis, which you specify in the block dialog.
The Inertia block has one port. You can connect it to a driveline axis by
Connecting the port to the end of the axis
Branching a connection line off the main line and connecting it to the port
Caution: Normally, a rigid body along a driveline has a positive inertia. You can also enter zero inertia for particular driveline bodies. If you do so, you must ensure that the effective inertia of your entire driveline is positive before actuating it with torques.
Rotational moment of inertia of the body represented by the
block. Must be a real, nonnegative number or MATLAB expression. The
units are kilogram-meters2 (kg·m2).
