The Basics of Vibration and Damping in Engineered Designs
Download this article in PDF format. Vibration is the periodic back and forth motion of the particles of an elastic body or medium.It usually arises when a physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.. The motion may be periodic, as in the motion of a struck pendulum.Web

How to Choose the Right Vibrator for Material Flow Problems
It may be necessary to apply several linear vibrators when the entire bin must be cleaned. If the object is to maintain material flow only, fewer vibrators may be used. Use the following guidelines for impacting vibrators: Wall Thickness of 0.7" to 0.125"; vibrator with 1-¼" piston. Wall Thickness of 0.125" to 0.25"; vibrator with 2 ...Web
