Wherein, the period of time can be 5 s-30 s. Specific values for the period of time may be defined as desired.
In the embodiment of the application, the dynamic balance equipment measures unbalance according to supporting vibration caused by unbalance of a main shaft or vibration force acting on the supporting under the condition that the main shaft rotates, and the physical quantity of the vibration is converted into an electric signal to be sent into a measuring system of the centrifugal balance equipment for processing after being detected by a sensor in the dynamic balance equipment, so that the position and the size of the measured unbalance are displayed.
It should be noted that, the detection of the unbalance amount by the dynamic balance device is a relatively mature technology in the art, and will not be discussed in detail here.
S3, after the centrifugal pendulum vibration absorber is subjected to weighting or de-weighting treatment through the unbalance data, the unbalance data of the centrifugal pendulum vibration absorber are re-measured by adopting the step S1 and the step S2.
