INTRODUCTION
Vibration refers to mechanical oscillations about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road. More often, vibration is undesirable, wasting energy and creating unwanted sound pollution. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations can be caused by imbalances in the rotating parts.
Imbalances in rotating parts are caused by unequal radial mass distribution on a rotor system, a shaft condition where the mass centerline does not coincide with the geometric centerline. Also, the effective mass causes the rotor to be out of balance. Other reasons may be uneven friction, the meshing of gear teeth, etc.
Alignment also plays an important role in the health of the rotary equipment. While carrying alignment Skill, time management and place plays a vital role in the upkeep, availability, and reliability of the rotating equipment.
The Asset Effectiveness relates to extracting maximum profits from the minimum investment in plant and equipment, improving Equipment Reliability through the effective prediction (and then avoidance) of equipment failures and minimizing downtime through the integrated planning and scheduling of repairs indicated by Condition Monitoring techniques with those indicated by other techniques.
The present programme aims at attending to the above issues.
