Friction

Drive train with clutch and brake

Diagram

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This drive train contains a frictional clutch and a brake. Simulate the system for 1 second using the following initial values (defined already in the model):

inertia1.w =  90 (or brake.w)
inertia2.w =  90
inertia3.w = 100

Plot the output signals

tMotor      Torque of motor
tClutch     Torque in clutch
tBrake      Torque in brake
tSpring     Torque in spring

as well as the absolute angular velocities of the three inertia components (inertia1.w, inertia2.w, inertia3.w).
