We can explain this motion-law if we project the motion of a Point, that is at the end of a rotating Crank, onto a Line.

When a Crank rotates with Constant angular velocity, the motion of a Point that we project onto any Line is Simple-Harmonic-Motion.

When the Crank rotates with the CV-Inverse-Crank motion-law, the motion of a Point that we project onto a particular Line is Constant Linear Velocity.

Start Position - control with the Segment-Parameters - see below.

End Position - control with the Segment-Parameters - see below.

Start Velocity and End Velocity

Start Acceleration and End Acceleration

Start Jerk and End Jerk

The actual velocity, acceleration, and jerk values, and the distance the Point moves along the Line are a function of the:

•Segment-Width

•Length of the Rocker/Crank

•Segment-Parameters

The Segment-Parameters are ANGLES:

Min Vel (Minimum Velocity)

The Angle relative to the Base-Value angle that you control with the Motion-Dimension FB at which the Crank rotates with Minimum-Velocity.

Rel Start (Relative Start)

The angle, relative to the angle you control with Min Vel, at which Point starts to move along the Orange Line with Constant-Velocity.

Rel End (Relative End)

The angle, relative to the angle you control by Min Vel , at which Point ends the move along the Orange Line with Constant-Velocity.

Note:

The Crank rotates Counter-Clockwise when Rel. Start is Negative and Rel. End is a Positive.

The Crank rotates Clockwise when Rel. Start is Positive and Rel. End is Negative.
