Watt Linkage

Using the rigid link between the double rockers, a short and smooth approximate straight line segment is obtained at the center of the figure-eight trajectory.

Indicator description

The system performs a sliding search over the complete output trajectory and automatically identifies the optimal 30% operating interval with a least squares straight line fit. Velocity fluctuations are calculated based on the projected displacements of adjacent samples in the interval.
