Abstract

Today, tire performance becomes better as vehicle performance increases. Driviability, endurance, comfortability, noise, and antiwear performance is influenced by tire contour. Tire design method is developed by high-tech engineering technology. Among theses studies, tire performance improvement through tire contour optimization is performed by many vehicle investigator. Therefore, in the present study, an optimum contour design system satisfying the tire performance requirements is constructed by regression analysis and genetic algorithm by using design of experiments.

오늘날, 차량의 성능 향상에 따라 타이어에 대한 요구가 다양화 되고 요구성능이 고도화됨에 따라 타이어의 설계기술에 보다 다양한 기반기술들이 적극적으로 사용되기 시작하였으며, 이에 대한 많은 연구 중 타이어 형상의 최적화를 통한 타이어 성능 향상을 위한 연구들이 활발히 진행되고 있다. 타이어 형상은 운전성능, 회전저항성, 내구성, 승차감, 소음, 내마모성 등과 같은 차량의 주요성능에 직접적인 영향을 미치는 대단히 중요한 설계인자이다. 따라서 본 연구에서는 실험계획법의 하나인 직교배열표와 회귀식을 이용하여 타이어 형상설계 시에 필요한 유한요소 해석시간을 단축시키고 유전자 알고리듬을 이용하여 타이어의 주요 성능을 만족하는 다목적 형상최적설계를 수행하였다.
