Research on the Frequency Characteristics of Transmission Torsion Amplitude for Wide and Thick Plate Hot Rolling Mill with Vibration Isolators
In order to further improve the stability of the transmission system of the wide and thick plate hot rolling machine,vibration isolators are used to reduce the amplitude frequency characteristics of the equipment.Then,the torsional amplitude frequency changes formed by the transmission system of the wide and thick plate hot rolling machine are simulated and tested under various torsional stiffness.The results showed that after using the isolator,the transmission system generated smaller torsional displacement,recovered from an unstable state to a stable state in a short time,and was able to enter the stable cycle faster.By appropriately increasing the inertia ratio of the isolator,a smaller amplitude frequency can be obtained and the curvature can be reduced.Setting the inertia ratio to 0.2 is more reasonable.In addition,the isolator also has advantages such as high damping and long service life,which can effectively regulate the torsional vibration frequency of the rolling mill transmission.
