It is shown how to model and simulate frictional effects present in gearboxes and in planetary gearboxes. This includes modeling of gear wheel stucking and sliding due to Coulomb friction between the gear teeth leading to load torque dependent losses. This allows reliable simulation of, e.g., stick-slip effects in servo drives or gear shifts in automatic gearboxes. It is also discussed how the friction characteristics can be measured in a useful way. The presented models are implemented in Modelica and demonstrated at hand of the simulation of an automatic gearbox.
