Vibration AnalysisVibrating Screens: TheoryPractice
2016-4-6 Vibration Analysis (VA) is a key technique used for maintenance and fault detec tion of vibrating machinery. The purpose of maintenance is to analyze how well the machinery is operating within its target parameters, while fault detection is done to diagnose and locate a fault that might be developing on the machinery.

Measuring Vibration: The Complete Guide BrüelKjær
A body is said to vibrate when it describes an oscillating motion about a reference position. The number of times a complete motion cycle takes place during the period of a second is called the frequency and is measured in hertz (Hz). The motion can consist of a single component occurring at a single frequency, as with a tuning fork, or of

Calculating the G-force of a Vibrating Screen
2015-7-8 n = number of poles of the motor. Once the motor speed has been calculated, the G-force can be calculated using this formula: G-force = (Stroke X w^2) / 1.8 X 10^6. where: Stroke = measured amplitude in mm. For optimal efficiency, a G-force of 4.5 5.0 will supply sufficient acceleration to the feed to not clog or peg in the screening interface.
