Conclusions
1. The motion pattern of tilting and beam-column accounted for more than 70% of all four motion patterns, indicating the importance of these two motion patterns in removal of cherry fruits.
2. Vibration at 14 Hz had the lowest fruit damage percentage, mainly due to the high percentage of fruit motion in beam-column motion pattern.
3. Lower vibration frequency resulted in more low-level damage with longer detaching time, while higher frequency resulted in more high-level damage.
