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. Segment-Parameters - for pseudo Modified-Sinusoid ![]() Segment-Parameters (Harmonics 1,2,3) for a pseudo Modified Sinusoid motion-law. |
![]() Pseudo Modified-Sinusoid motion-law from 3 Harmonics. |
SummaryThis 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. |
