실험과 해석을 통한 종이의 정적, 동적 거동에 대한 물성치 추정 정적 처짐과 동적 거동에 대한 실험과 시뮬레이션을 통한 종이의 물성치 추정 (Material Property Estimation of Paper Using Correlation between Experimental and Analytical Results of Static and Dynamic Behaviors)
Abstract :
This thesis proposes a technique to estimate the material property of a paper by using an experimental methods and corrlation of commercial CAE software. Under gravitation, if one side of the paper is attached to the ground, the opposite side of paper is largely deformed, and vibrates freely. Since the paper has an orthotropic characteristic due to its treatment, the deformations in two orthogonal directions of the dry paper are different. This phenomenon introduces an experimental method to measure the static deformation of the paper with the orthotropic characteristics and dynamic behavior. And then, virtual prototypes that can represent the static and dynamic behavior are modeled by using the commercial CAE software RecurDyn^(TM)/MTT3D, which has been widely used by the printer makers. While comparing the deformation and frequency from the experiment and simulation, a design optimization technique in the commercial CAE software of R-INOPL, RecurDyn^(TM)/AutoDesign is used to estimate the material property such as Young's modulus, shear modulus and density of the paper.
