What are the applications of vibration?

Examples of beneficial applications of vibrations include ultrasonic probes, both for medical application and for nondestructive testing. The picture shows a medical application of ultrasound: it is an image of someone’s colon.

What is equipment vibration?

In simplest terms, vibration in motorized equipment is the back-and-forth movement, or oscillation, of machines and components, such as drive motors, driven devices (pumps, compressors and so on), and the bearings, shafts, gears, belts and other elements that make up mechanical systems.

What are the equipments used to measure vibration?

Vibrometers are instruments that receive the electrical signal from a transducer and process it, applying filtration and integration, to obtain the overall vibration level value in velocity. Most of them are designed to take measurements according to certain standards of vibration severity.

What are some examples of vibrations?

Examples of these types of vibration include a washing machine shaking due to an imbalance, transportation vibration caused by an engine or uneven road, or the vibration of a building during an earthquake.

What is the importance of vibration?

Most of the results arising due to vibration lead to failures, damage of equipment and in worst cases loss of life. Knowing more about vibration helps us to control damage and take preventive measures from damages to occur. Free Vibration: This is a type of vibration which can neither be induced nor stopped.

What are vibrations engineering?

the aggregate of methods and facilities for the generation of mechanical oscillations (vibrations) in the frequency range from about 10 megahertz to 10 kilohertz, as well as means for controlling the vibrations, measuring and monitoring them, and preventing harmful vibrations.

How is vibration useful in preventive maintenance?

It is one of the tools in the predictive maintenance (PdM) tool kit. Vibration analysis helps conduct condition monitoring to identify potential failures, which ultimately saves money by: Reducing unplanned downtime and scheduling work that fits an organization’s plans.

Why does a machine vibrate?

Machine vibration is a normal, and typically unavoidable, result of moving and rotating parts, often caused by standard manufacturing and assembly tolerances that lead to clearances between mating parts or imbalances in rotating parts. Shaft misalignment is a common cause of machine vibrations.

Which instrument is used to measure the vibration of induction motor?

Strain gauges are used especially at force measurements, but vibrations are produced by forces, it means they can be used at vibration measurements.

Why is rubber used as vibration absorbers?

Rubber is used as vibration absorbers, because rubber has a relatively high shear modulus compared to other materials. That means when a rubber material is shear stressed, i.e. stressed parallel to its cross-section, rubber can be stressed more before it becomes permanently deformed.

What causes objects to vibrate?

When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy.

What is a vibration analysis equipment?

A vibration Analysis Equipment is an instrument used to measure, store and and diagnose the vibration produced by your machines. Vibration analysis equipments use FFT based tools to measure frequencies and identify the causes that originate them. You can find some examples here:

What are the applications of a vibration sensor?

These sensors are used for curved surfaces. When mass and size are significant, then strain data is required. These sensors are used for high-temperature applications like above 700 °F. These sensors are used where orientation information is necessary. These sensors are used for health monitoring, as well as to determine vibration frequency.

What are the effects of vibrating machinery?

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. In the worst cases, vibration can damage equipment so severely as to knock it out of service and halt plant production.

When should you perform a vibration analysis of Your Piping System?

Piping that transports fluid, equipment that cycles between different temperatures and pressures, and rotating equipment are among the most susceptible components to experience vibration. This analysis should be performed shortly after start-ups and repairs to ensure equipment is operating within integrity operating windows.
