Information

This model contains bearing friction and gear friction (= efficiency). If both friction models are stuck, there is no unique solution. Still a reliable Modelica simulator should be able to handle this situation.

Simulate for about 0.5 seconds. The friction elements are in all modes (forward and backward rolling, as well as stuck).

You may plot:

Inertia1.w,
Inertia2.w          : angular velocities of inertias
powerLoss           : power lost in the gear
bearingFriction.mode:  1 = forward rolling
                       0 = stuck (w=0)
                      -1 = backward rolling
gear.mode           :  1 = forward rolling
                       0 = stuck (w=0)
                      -1 = backward rolling

Note: This combination of LossyGear and BearingFriction is not recommended to use, as component LossyGear includes the functionality of component BearingFriction (only peak not supported).
