| 英文摘要: |
| Two rollers contact each other under the normal load, and when the driving roller rotates, it drives the driven roller rotate by the tangential force on contact area. Finite Element Method analysis and experimental analysis are adopted to research the motion mechanism of two rollers which elasticity has big difference both on the condition of direct contact and indirect contact. From the analysis it is achieved that the relative sliding between the two rollers is due to the tangential force on the contact area and the radial compression deformation of the soft roller which has greater elasticity. For the condition of indirect contact in which a layer of inter-medium exists between the two rollers, the relative sliding is greater than that on the condition of direct contact, and the hardness of the inter-medium layer affects the relative sliding between the two rollers. And for the condition of multiple rollers in the state of pressing contact, the number of contact areas on the soft roller also affects its motion characteristics. |
