非線形接触特性と粘弾性を考慮した紙の圧縮変形挙動のモデル化

抄録

In mechanical systems that handle paper such as printers and paper making machines, paper is conveyed by friction caused by contact between the paper and the machine components. Since this conveying performance by friction seems to be greatly influenced by compression situations, it is important to comprehend the compression properties of paper. In this report, a new model of compression of paper has been proposed considering nonlinear contact properties and viscoelastic deformation properties. Nonlinearity is modeled as a contact model of rough surfaces in which asperities of surface roughness composed of entangled fibers are distributed in the perpendicular direction to the surface. Viscoelasticity is modeled as a 3-element viscoelastic solid model by which delayed elastic deformation can be expressed. An identification method for the proposed model using experimental data measured under several loading ratios has been introduced and applied to a typical measured data to find its validity.
