Fatigue failure analysis of vibrating screen spring by
Vibrating screens are often used in the mining industry to separate mineral particles by size. In many designs spring arrays are used to provide the system with the necessary stiffness for screens to vibrate in a controlled manner. Naturally these springs are subjected to varying loading cycles which can cause their premature fatigue failure.

Tuning is a process used to eliminate amplification due to resonance by changing a system or component natural frequency fn so that it is no longer coincident with the frequency of a specific force input. Resonance of industrial equipment will amplify vibration response in theory up to ∞ depending on system damping characteristics.
Sometimes these vibrations cause minor or serious performance or safety problems in engineered systems. For instance when an aircraft wing vibrates excessively passengers in the aircraft become uncomfortable especially when the frequencies of vibration correspond to natural frequencies of the human body and organs.
