Abstract

Side bolster is a part of the vehicle seat that holds the passenger's body from the side to make it more stable when the passenger is seated in the seat. In this study, the structural and fatigue analyses of the side bolsters at a car seat were carried out with two models of A and B. The heavily loaded parts, the damage by fatigue at driving a car and the difference of durability due to the structure were examined and the distributions of stress and deformation, and the fatigue lives were seen. Also, the strength and durability were examined. This study result is thought to be devoted to decrease the fatigue damage and increase the fatigue life and durability according to the design of bolster. This result is able to improve the product by applying the design of automotive side bolster practically. And it is thought to be the advantage to apply this study result to the convergence research with esthetic sense.

사이드 볼스터는 자동차 시트에서 탑승자가 시트에 착석하였을 때, 더욱 안정성을 줄 수 있도록 옆에서 탑승자의 몸을 잡아주는 부품이다. 본 연구에서는 A, B 두 가지의 모델을 가지고 자동차 시트에서 사이드 볼스터에 대한 구조 및 피로해석을 수행하였다. 하중이 많이 실리는 부분과 자동차 운행 시 피로로 인한 파손 및 구조에 따른 내구성의 차이를 연구하였고 응력, 변형량의 분포 및 피로 수명을 알아보았으며 또한 그 강도 및 내구성을 검토하였다. 본 연구 결과는 사이드 볼스터의 설계에 따라 피로 파손을 줄이고 그 피로 수명 및 내구성을 증가할 수 있는 데 기여가 될 것으로 사료된다. 그리고 본 결과를 자동차 사이드 볼스터의 설계를 실제적으로 적용함으로서 제품을 향상시킬 수 있고 본 연구결과를 미적 감각을 가진 융합 연구에 응용하는 것이 유리하다고 사료된다.
