Modified sine with X% constant velocity

This profile is the modified-sine profile with a fraction of the total segment allotted to constant velocity.


Modified-Sine X% C.V. Properties

The displacement is linear (uniform rise or fall) in the constant velocity portion.

The displacement and velocity curves have zero slope at the ends.

The curves are symmetrical; therefore, the displacement at the mid-point is 1/2 the total.

The modified-trapezoid X% C.V. profile (figure 8) has a linear velocity region where the acceleration is constant.



1.These curves in Figure 7 are drawn for a positive displacement of the follower.  A negative displacement will result in a mirror image of the graphs about the x-axis.

2.The X axis is θ/β from 0 to 1

3.The Y axis is based on a displacement of 1.
