FE Analysis for Tread Forming of Tire by Using an Adaptive Mesh Refinement

적응적 요소 재구성을 이용한 타이어 트레드 성형의 유한 요소 해석

Automobile tire has very complicated shape and is composed of rubber, steel cord and ply cord, Tread pattern of tire is very essential for the basic characteristics of tire, such as braking, acceleration and comfortableness. Tire components such as tread, sidewall, and spex are prepared by forcing uncured rubber compound through an extruder to shape during curing process. Because of its complexity of shape, adaptive mesh refinement was used for the analysis of tire tread. Effects of forming variables were evaluated.
