Triple-Harmonic: Modified Sine Motion-Law

Triple-Harmonic: Approximate Modified Sine

To use this Motion-Law:

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

2.Open the Segment Editor.

3.Edit the Segment Parameters:

First Harmonic = 5.1968

Second harmonic = 1.7690

Third Harmonic = 0.6057

MotionDesigner calculates the Third harmonic, based on the fact that the segment always creates a Dwell-Rise-Dwell type segment.

Summary

This motion-law is continuous and symmetrical.

It is near to the traditional Modified Sinusoid Acceleration Cam-Law.

However, because it has only three harmonics, it is smoother at the higher derivatives.

The maximum velocity is slightly lower and the nominal acceleration is slightly higher than the Modified-Sinusoid mot. law.
