Open Differential Testrig

This example models an open differential using multiple bevel gears. This gearset enables the axles to rotate at different speeds even though they are connected to the same input shaft

The Bevel Gear Constraint requires that the rest of the mechanism hold the two frames to which it is connected in alignment. This subsystem has the necessary constraints and parameterized Rigid Transforms to hold the frames in the right position and orientation.

The plot below shows the input shaft and axle shaft speeds. A step change to the load on one of the axles causes the two axles to spin at different speeds.
