This motion is approximately equal to the Modified-Trapezoidal motion-law.

1.Select the Triple Harmonic in the Motion-Law Selector

2.Open the Segment Editor.

3.Edit the Segment Parameters:

•First Harmonic = 6.04 (optionally 5.96)

•Second Harmonic = 0.0

•Third Harmonic = 0.7296 (optionally 0.9696)

We calculate the third harmonic for you, based on the fact that the segment always creates a D-R-D segment.

Summary

This law is continuous to Acceleration.

The output motion is near to the traditional Modified Trapezoidal Acceleration Cam-Law. However, it can be described by one mathematical function.

The maximum velocity is the same as the traditional law, but the nominal acceleration is slighter greater.
