As is shown in Figures 3(a) and 3(b), with the increase of nonlinear friction, the peaks and troughs of the vertical vibration curve of the rolling mill system showed irregular vibration. It can be seen from Figures 3(b) and 3(c) that when the nonlinear spring force is increased, the vibration curve of rolling mill system has various irregular vibration.

Vibration issues of a fivestand tandem cold rolling mill were found in the steel production practice, and the experimental observation and numerical analysis indicated that the vibrations were related to the backup roll bearing. The results were validated by replacing the backup roll bearing with the new bearing resulting in 30% decline in vibration amplitude. Models describing the fourrow ...

Moreover, we discussed how the dynamics of the spindle are affected by the eccentricity of the belt pulley, the extended length of the milling tool, and the position of the intermediate bearing set. The research results can benefit the structural design of the spindle, optimize the bearings selection, as well as improve the machining accuracy.

In the example from the September 2012 article, the vibration response at the top motor bearing was twice the vibration at the motor CG. This is fairly typical for such installations. The peaktopeak vibration at the topofmotor bearing is 4X (inches). To express in mils, the vibration at the topofmotor bearing is (4X/1,000).
