Device for predicting deformation behavior of rubber material and method for predicting deformation behavior of rubber material

A device for predicting a deformation behavior of a rubber material, comprising:

• means for obtaining a plurality of sliced images each showing a cross-sectional shape of the rubber material formed by adding a filler to a rubber;
• means for converting each of the sliced images to be a binary-converted image to distinguish between a rubber portion and a filler portion contained in the rubber material;
• means for setting, in the binary-converted image, a rubber layer portion adsorbed with the filler, and converting the binary-converted image into a three-layered image;
• means for layering the three-layered image to generate a three-dimensional model of the rubber material;
• means for applying a configuration condition specified on the basis of a molecular dynamics approach to the three-dimensional model;
• means for analyzing a deformation behavior of the rubber material using the three-dimensional model to which the configuration condition is applied, wherein the means for analyzing the deformation behavior of the rubber material performs analysis by applying a finite element method to the three-dimensional model to which the configuration condition is applied;
• and,
• means for presenting a result of the analysis of the deformation behavior of the rubber material, wherein
• the configuration condition specified on the basis of the molecular dynamics approach is a configuration condition specifying a relationship between a stress and a strain on the basis of thickness information and temperature information of the rubber layer portion obtained on the basis of the molecular dynamics approach,
• wherein the thickness information comprises information including a relationship between a distance from a filler surface and a diffusion coefficient of the rubber material, and
• wherein the temperature information comprises information including a relationship between a temperature and a diffusion coefficient of the rubber material.
