Application of Dynamic Balance Spectrum Analysis Functionvibration analysis:

The main function is to enable users to analyze whether the vibration source is caused by the imbalance of the rotor body before using dynamic balance correction.(chart1)Regardless of the speed of the rotor, the line on the first grid (first harmonic) of the X-axis indicated by the arrow will always be the vibration generated by the imbalance of the rotor body(1chartIt was before the balance was calibrated)

.(chart2)It can be clearly seen that the vibration source is not the vibration caused by the imbalance of the rotor body, but rather the vibration source caused by other components(2chartCorrected balance)

.Vibration analysis, such as(chart1)

As shown, the dynamic balance correction function can be further used.Vibration analysis, such as(chart2)Please do not use this as shown

Dynamic balance correction requires users to analyze whether the vibration source is caused by other components.

Principle of rotor dynamic balance:
Machinery contains a large number of components that move by rotation, such as various transmission shafts, main shafts, electric motors, impellers, and turbine rotors, collectively referred to as rotating bodies.


In an ideal situation, the pressure exerted on the bearings is the same when the rotating body rotates and when it does not rotate, making it a balanced rotating body.

Uneven material of the rotating body generates vibration and noise
Due to various factors such as uneven material or blank defects, errors in processing and assembly, and even asymmetric geometric shapes in design, various rotating bodies in engineering can be affected,
When the rotating body rotates, the centrifugal inertia force generated by each tiny particle on its surface cannot cancel each other out. The centrifugal inertia force acts on the machinery through bearings, causing vibration and noise,

And accelerating bearing wear shortens mechanical life, which can cause destructive accidents in severe cases.

Causes of vibration:


Factors such as imperfect materials, manufacturing precision limitations, and wear and tear after use can cause vibration in moving objects.The rotor must be balanced to achieve the allowable balance accuracy, and the mechanical vibration amplitude generated must also be reduced within the allowable range
