Dog Clutch
Dog Clutch component
The Dog Clutch component models a clutch where the coupling of the two sides is achieved by the engagement of toothed connections between the two shafts (as opposed to friction in normal clutches). A typical usage of dog clutches is in manual transmissions.
Geometry
The Dog Clutch geometry is defined by two parameters; and as shown in the figure below.
Equations
and
The contact between the teeth on the two sides of the Dog Clutch is modeled using linear angular springs and dampers:

State Machine Definition
The Dog Clutch has three distinct states as shown in the figure below.
