B.9.1 Changing an external force
Changes in an external force may cause vibration or even
bouncing on a stop.
Example:
ć Cylinder1: DNCI−32−250 horizontal 16 kg
ć Cylinder2: for counteracting force from 160 mm of
approx. 350 N constant

1
1st record: F = 430 N −−> Cylinder1 moves cylinder2 until cylinder1 is in the stop.

2nd record: F = 200 N −−> Cylinder2 moves cylinder1 out of the stop to position
160 mm.
3
−−> This causes bouncing with 2 to 3 impacts.
