A Brief Tutorial on Machine Vibration by Victor Wowk, P.E. Machine Dynamics, Inc. The purpose of this tutorial is to provide sufficient knowledge to understand machine vibration diagnosis. You may be tasked with solving a vibration problem, or you may be overseeing someone else and you need to understand the process. Abstract: The most common source of vibration in a rotor is the unbalance amongst all other and it will be always present in the rotor system. The unbalance causes the vibration, acoustic noise, and excessive wear of bearings in a high speed rotating machines when it runs very close to its critical speed.
Vibration sensors are used to detect roller bearing wear, gearbox wear, shaft misalignment, unbalance, and mechanical looseness. Speed sensors work with vibration sensors to correlate vibrations to rotating speed and shaft angular position. Motor current sensors are commonly placed at the motor control center. Rotating Equipment Vibration Analysis. When your company is in machinery-intensive industries such as oil and gas production, hydrocarbon processing, electric power generation, pulp & paper, water and waste water treatment, you are familiar with the maintenance needs of turbomachinery equipment.
*Refers to constant speed machines. For variable speed machines, velocity severity is constant. Note from the chart that the displacement and acceleration measureands vary with speed and are not normally used due to complex severity determination. 20 - 30 um, pk-pk VIBRATION FREQUENCY IN CPM (e. g. MACHINE RPM) VELOCITY mm/s (IPS) (10) Prevent machinery failure and costly production downtimes! Our vibration measurement tools are used to check the condition of rotating equipment and detect early component wear and damage. Vibration analysis and balancing are integral parts of any condition-based and predictive maintenance programs.

Machinery Vibration Limits and Dynamic Structural Response Vibration monitoring of rotating machinery has developed over the years to the point where it is an accepted maintenance tool. Much effort has been applied towards developing guidelines regarding acceptable absolute levels of vibration.
Discussions of some of these standards and. Vibration is the behavior of a machine’s mechanical components as they react to internal or external forces.
Since most rotating machinery problems show themselves as excessive vibration, we use vibration signals as an indication of a machine’s mechanical condition.
Also, each mechanical. Vibration Analysis of Rotating Machinery; On this page; The rotating speed of the gear and output shaft is. f Gear = f Pinion An impact from a localized fault generates high-frequency vibrations in the gearbox structure between the bearing and response transducer .

This report describes a sudden change and increase in synchronous vibration amplitude of a stacked rotor for high temperature ( deg. C) high-speed (10, rpm) blade testing machine.
(Phenomena observed) The amplitude kept increasing with increasing shaft speed after it increased. The motion, caused by vibration, of a machine platform or skid can be measured and plotted in a manner similar to that outlined for the piping system.
It is not unusual to find a resonance of a platform being excited by a machine's running speed. This is especially true after modifications to the machinery have been made. The effects of vibration can be severe. 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.Whether or not a rotor is classified as rigid or flexible depends on the relationship between the rotating speed (RPM) of the rotor and its natural frequency.
When the natural frequency of some part of a machine is also equal to the rotating speed or some other exciting frequency of vibration, there is a condition of resonance. High-speed balance compensates for the true distribution of unbalance along the rotor, meeting a limit at maximum continuous speed but also considers the force at the first critical speed.
After a high-speed balance the measurement in a low-speed balance machine often exceeds 4W/N. Thus a suggested modification to the low speed balance limit.
