Considering the two kinds of nonlinear constraints of rolling mill hydraulic cylinder, spring force and friction force, the vibration model of rolling mill system is established. The amplitude frequency response equations are obtained by using the average method. Comparing the time history curves of vertical vibration displacement of rolling mill system under the nonlinear spring force and ...

Control of third octave vibrations in a mill stand can be achieved using a highspeed piezoelectric assist coupled to a hydraulic gap cylinder to increase the damping of the roll stack. Vertical movements of the roll stack (, the top work roll) can be determined through observation (, measurement) of hydraulic fluid pressure of the hydraulic cylinder or entry tension of the metal strip.

Basic Safety Checks for Hammer Mills. In terms of safety checks, Jim recommended the following: Using a magnetic separator to ensure that tramp metal doesn't come into the mill itself. Prevent buildup in the grinding chamber, so that heat doesn't create a source of ignition. Checking to make sure that the bearings are not running hot.

Both figures refer to the initial roll angle of Φ0=10o. The contours are plotted against the four ratios of instantaneous time to natural period of the model. The attachment of bilge keel increases the roll damping and the roll natural period of the model. The increase in the roll damping is mainly due to the forces acting on the bilge keel.

Performance with an ADD is an additive process, so the more devices you attach to the structure or machine, the more vibration reduction you get. An ADD does not need to be tuned to the respective target resonance. Compared to passive Tuned Mass Damper, ADD are usually lighter and better performing.
