What are the applications of mechanical vibration in industries?
Applications for electric and pneumatic industrial vibrators and vibratory equipment span almost all stages of production processes across all industries relying on bulk materials. Industrial vibrators and vibratory equipment can be effectively used to reduce costs and improve production quality.
What are mechanical vibrations?
Mechanical vibration is defined as the measurement of a periodic process of oscillations with respect to an equilibrium point. Attention will be paid to vibrating systems such as beams, strings, plates and membranes, vibration isolation, critical speeds, the balancing of rotating and reciprocating machinery.
What are the types of mechanical vibration?
A vibrating motion can be oscillating, reciprocating, or periodic. Vibration can also be either harmonic or random. Harmonic vibration occurs when a vibration’s frequency and magnitude are constant. A vibration is random when the frequency and magnitude vary with time.
What is vibration in industries?
Vibration in industrial equipment can be both a sign and a source of trouble. In some tasks, vibration is essential. Machines such as oscillating sanders and vibratory tumblers use vibration to remove materials and finish surfaces. Vibratory feeders use vibration to move materials.
What is the importance of studying vibration engineering?
The primary goal of vibration analysis is to identify faults within a machine and then alert personnel that some type of action needs to occur. Problems start to occur when the needed frequency of the data collection is not aligned with the maintenance strategy.
Why is it necessary to study mechanical vibration?
What is the importance of mechanical vibrations?
Rotating machine parts need careful balancing in order to prevent damage from vibrations [8]. The worst impact has resonance of mechanical systems. Resonance can occur when forced vibration and can cause even at low loads serious damages. Understanding of vibrations is therefore very important for engineers.
What is the importance of vibration to mechanical engineering design?
What are the effects of vibration in mechanical engineering?
Unchecked machine vibration can accelerate rates of wear (i.e. reduce bearing life) and damage equipment. Vibrating machinery can create noise, cause safety problems and lead to degradation in plant working conditions. Vibration can cause machinery to consume excessive power and may damage product quality.
What are the causes of vibration in mechanical components?
Vibration can be caused by one or more factors at any given time, the most common being imbalance, misalignment, wear and looseness. Imbalance – A “heavy spot” in a rotating component will cause vibration when the unbalanced weight rotates around the machine’s axis, creating a centrifugal force.
