To optimal, peak-to-peak value as shown by data is tested, under certain charge oil pressure, with the reduction of metal-rubber lumpiness coefficient, and damping
The increase of coefficient, better, fundamental vibration amplitude gradually declines metal-rubber dry-friction damping effect, with the increasing of charge oil pressure
Plus, the damping shock absorber effectiveness in vibration suppression is more obvious, and peak swing declines.
A kind of vibration control method, it is used for above-mentioned supporting shock absorber, comprised the following steps：1. described in velocity measuring dress
Put the rotating speed S1 of detection high speed cone axis 1 and be transmitted to MCU（Main control circuit）；2.MCU determines high according to default speed interval
It is interval which the rotating speed of fast cone axis 1 is in, and is high velocity, middling speed area, or low velocity area.3. it is interval according to friction speed,
The oil pressure value in correspondence interval is exported to fueller, the oil pressure for making fueller change in bearing shell 2 is corresponding to adapt to cone axis 1
Rotating speed.
