Testing the vibration damping of a glass gatherer robot arm using a friction damper

This paper describes a test stand along with a model of a lance used in glass works. A prototype friction damper was used for vibration damping of the lance. Experimental tests were conducted, whose aim was to determine operating conditions under which the damper will be the most effective. Damping was evaluated based on the damping decrement determined using the resonance curve for the first form of vibration of the lance. It was found that a friction damper has optimal values of preload force from the point of view of damping of the lance's resonant vibration.
