REVISED SIEVERS LATERAL DYNAMICS MODEL

REVISED SIEVERS LATERAL DYNAMICS MODEL by R. L. Walton Eastman Kodak Company USA NOMENCLATURE A=cross-sectional area E=Young's modulus G=shear modulus I=area moment of inertia J=inertia per unit length m=mass per unit length n=shear factor t=time T=total tension v=web longitudinal velocity x=longitudinal position y=lateral position z=lateral position of a roller in a displacement guider frame (otherwise zero) 0 =face angle (centerline angle plus shear angle) 0, =roller misalignment angle (zero if perfectly aligned) Dots above variables indicate time derivatives Apostrophes following variables indicate spatial derivatives with respect to x 473
