KM Will Share With You How To Choose The Vibration Measurement Parameter Unit Of The Vibration Analyzer?

Vibration measurement is an important technology that can help us understand the operation and problems of mechanical equipment. Selecting the correct parameter is critical when performing vibration measurements as it directly affects the accuracy and reliability of the results. First of all, we should clarify what parameters are involved in vibration measurement.

Generally, vibration analyzers use three parameters, including vibration displacement (um), vibration velocity (mm/s) and vibration acceleration (g). In practical applications, we usually choose according to the purpose of monitoring.

The following will introduce the selection of three vibration parameters (units):

1. Vibration displacement value

If you need to pay attention to the position accuracy of equipment parts or damage caused by deformation, you should choose the peak value (or peak-to-peak value) of vibration displacement, because the peak value reflects the limit value of position change;

2. Vibration acceleration value

If the focus is on the effects of inertial forces, acceleration should be selected because acceleration is proportional to inertia;

3. Vibration velocity value

If the focus is on the fatigue damage of the part, the RMS of the vibration velocity should be selected, because the fatigue life mainly depends on the deformation energy of the part and the cycle speed of the load, and the RMS of the vibration velocity is just their reflection.

When choosing a unit for a vibration measurement parameter, we should consider the following:

1. International Standard System of Units

The units of vibration measurement parameters should conform to an international standard system of units, such as the International System of Units (SI) or other globally accepted standard system of units.

2. Characteristics of mechanical equipment

The characteristics of different mechanical equipment are different, so the units of their vibration measurement parameters will also be different. When selecting a unit for vibration measurement parameters, the characteristics of the mechanical equipment should be considered to ensure accurate and reliable measurement results.

3. Actual measurement requirements
In the actual measurement process, we need to select the unit of vibration measurement parameters according to actual needs. If we need to measure the vibration velocity of the machine, we can choose units such as m/s or in/s; if we need to measure the vibration acceleration of the machine, we can choose units such as m/s² or in/s².

When performing vibration measurement, it is very important to correctly select the unit of vibration measurement parameters. We should choose the appropriate unit according to the specific situation to ensure the accuracy and reliability of the measurement results. By choosing units reasonably, we can better understand the operation conditions and problems of mechanical equipment, and then take corresponding measures to improve equipment performance and service life.
