Vibration isolation

At certain range of frequencies, motors, fans and compressors produce a vibratory force which really irritates human beings. As a result of this vibratory force, fasteners of machines loosen with excessive wear and tear of bearings. Formation of cracks is another adverse effect. These adverse effects may even lead to structural and mechanical failures including electronic malfunctioning. To minimize these unwanted effects, shock absorbers are introduced in vehicles. Shock absorbers employ vibration isolation techniques. A vibration isolation system makes use of theory of forced vibration. A dampener and a spring are used in a passive isolator. A servomechanism with a sensor, processor and an actuator forms an active isolator. Excessive vibration in a system can be controlled by using a vibration neutralizer or dynamic vibration absorber. Another spring-mass system is used for this.
