Chapter 5 Vibrations

Chapter 5 Vibrations Examples of practical vibration problems . Vibration is a continuous cyclic motion of a structure or a component. Generally, engineers try to avoid vibrations, because vibrations have a number of unpleasant effects: • Cyclic motion implies cyclic forces. Cyclic forces are very damaging to materials.

Machine Vibration Isolation – Theory and Practice

Machine Vibration Isolation – Theory and PracticeA reduction in vibration severity of 80% is required. Solution: The Isolation Efficiency Chart advises that for a disturbing frequency of 720 RPM and an 80% reduction in vibration severity the frequency of the new arrangement must be about 5 HZ. This will require a 10mm static deflection of a supporting isolation system.

Maintaining support springs in vibratory equipment

Maintaining support springs in vibratory equipment · Poor motion in vibrating screens and feeders can occur for many reasons, but one is arguably the easiest to prevent and yet seems the least understood – the adverse effect of support springs (the springs on which the machine sits) behaving differently from one side of the machine to the other. The motion of the equipment will vary between the left and right .
