This model contains two inertias which are connected by an ideal gear where the friction between the teeth of the gear is modeled in a physical meaningful way (friction may lead to stuck mode which locks the motion of the gear). The friction is defined by an efficiency factor (= 0.5) for forward and backward driving condition leading to a torque dependent friction loss. Simulate for about 0.5 seconds. The friction in the gear will take 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
gear.mode : 1 = forward rolling
0 = stuck (w=0)
-1 = backward rolling
Note, powerLoss (= sum of the power flows of the connectors) and
gear.powerLoss (= gear.tau_loss*gear.w_a,
where gear.tau_loss is determined in a non-trivial way
from the stuck/sliding situation of the bearing and teeth friction;
= equation (16) in [Pelchen2002])
should be identical, or the difference should be close to zero, if model
LossyGear
is correctly implemented.
