Optimization Procedure and Toolchain for Roll Dynamic Geometry

In rolls manufactured from first bent and then welded sheets of steel, the asymmetric distribution mass due to weld seam as well imperfections geometry bending may cause roll cross-section roundness profiles deform centrifugal forces when is accelerated rotate at its operating speed. This effect known dynamic roll. previous research, it has been shown that possible measure in speed compensate for deformation by grinding a suitable opposite on direct approach work only little material removed. Such conditions apply especially polymer coated rolls, where mostly dependent much stronger denser steel body under cover. paper goes further investigate possibilities compensating cases amount removed significant enough have an itself altered stiffness. The presents toolchain consisting parametric CAD model, finite element simulation optimization procedure based minimizing target function describing errors cross-sections Results experiments case example indicate presented can be used eliminate related Finally, discusses application such manufacturing rolls.
