PROPAGATION OF STRAIN WAVES AND COMPACTION OF A VISCOELASTIC MATERIAL BY A CYLINDER ROLLING OVER IT
D. I. Zolotarevskaya UDC 539.379.24:631.431.73:001.573 This paper considers problems on the rolling of rigid driven and driving cylinders slipping on a compactible viscoelastic base. As a result of the investigation of the process of propagation of viscoelastic decaying strain waves in a deformable medium caused by a cylinder rolling over it and the action of the sliding friction forces, formulas and calculation algorithms have been obtained for determining the indices of the stressed-strained state and compactness of the base, the rolling resistance of the driven and diving cylinders, and the driving force of the driving cylinder. Calculations of these indices have been performed for the cases of cylinders rolling over a soil whose viscoelastic properties have been investigated experimentally.
