Simulation of roll grinding system dynamics with rotor ...

2002-9-1  The grindstone is positioned to the middle of the roll (f 1 (z)=1) that is grinding stationary, and the roll has no shape error. Grinding starts after 1 s and the delay is considered after 7 s. The vibrations of the earlier rotation rounds keep in the deformation history of the roll surface and appear again for each new rotation round.
