METHOD, APPARATUS, AND PROGRAM FOR PREPARING MODEL FOR ANALYZING TIRE CORD, AND METHOD FOR ANALYZING TIRE PERFORMANCE

摘要

PPROBLEM TO BE SOLVED: To enable tire cord analysis to be conducted highly precisely on calculation. PSOLUTION: A model for analyzing tire cord is provided, through the following steps: Firstly, a tire cord is specified as a modeling object for preparing its analysis model (step 200). Secondly, filaments (cross-sections) of each layer in each twist direction, buffer layers between the respective layers are divided according to elements to prepare a two-dimensional model (step 202). Thirdly, the two-dimensional model is developed while being twisted and turned in the longitudinal direction from the inner layer toward the outer layer sequentially, and a three-dimensional shape is prepared (step 204).
