초록

본 연구에서는 차량의 승차감 향상을 위해 기존의 알루미늄 차량용 휠의 성능을 개선하고자 복합재료-알루미늄 하이브리드 휠을 제안하고 시제품을 제작하여 평가하였다. 유한요소해석 기법을 통해 알루미늄과 복합재료의 접착부에 대한 접착 길이와 접착 두께를 결정하고, 자동조심 및 접착 지그 역할을 할 수 있는 홈과 돌기 구조를 적용하였다. 차량용 복합재료-알루미늄 하이브리드 휠의 성능평가를 위해 다양한 실험을 유한요소해석을 통해 구현하고 안전성을 검토하였다. 복합재료 림 부의 성형을 위한 금형을 설계하고 진공백 성형방법으로 제작한 후 알루미늄 부와 접착을 하여 시제품을 완성하였다. 진동실험 결과, 동일한 형상의 알루미늄 휠보다 10% 가벼운 복합재료-알루미늄 하이브리드 휠의 경우 고유진동수가 16% 증가하였고, 감쇠능이 32% 증가하였다.

In this paper, a carbon fiber/epoxy composite-aluminum hybrid wheel for passenger cars was suggested for better performance and a prototype was fabricated and tested. Adhesive bonding between aluminum part and a composite rim part was used, and the bonding length and thickness were determined by finite element analysis. For self alignment and the function of bonding jig the special structure with a groove and a protrusion was applied. To evaluate the performance of the hybrid wheel various FE analyses were carried out. Inner and outer molds were prepared for the composite rim part and the thermoformed composite part was bonded to the aluminum part. Vibration tests revealed that the hybrid wheel had 16% higher resonance frequency and 32% higher damping capacity with 10% weight reduction.
