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).
