정적 처짐에 대한 실험과 시뮬레이션을 통한 종이의 물성치 추정

Abstract

This proposes a technique to estimate the material property of a paper using an experimental method and commercial CAE software. Under gravitation, if one side of the paper is attached to the ground, the other side is largely deformed. Also, since the paper has an orthotropic characteristic due to its treatment, the deformations in two orthogonal directions of the dry paper are different. This introduces an experimental method to measure the static deformation of the paper with the orthotropic characteristics. And then, virtual prototype which can represent the static behavior are built by using the commercial CAE software of RecurDyn™/MTT3D. The software has been used by engineers in printer makers. While comparing the deformations from the experiment and simulation, a design optimization technique in the commercial CAE software of RecurDyn™/AutoDesign is used to estimate the material property such as Young’s modulus and shear modulus of the paper.
