Couplings and Drives

Dynamic transfer of torques and motions

Couplings and drives blocks represent power transmission elements and systems such as springs, dampers, pulleys, and drives. To model the dynamic transfer of torques and motions, connect these blocks together just as you would assemble a physical driveline system.
