초록

자동차 구조 요소 설계에서 설계 엔지니어에게 주어진 가장 중요한 과업중 하나는 요소의 수명을 결정하고 그 요소가 좌굴하지 않도록 개선하는 것이다. 이렇게 하려면, 설계 엔지니어는 개념 설계 단계에서부터 부분 형상을 만들어 가기 위해 간단한 부분 해석을 먼저 시행해야 한다. 그리고 응력 레벨을 위한 보다 진보된 해석을 사용해야 한다. 이 단계에서 해석은 하중 경로와 총 응력 레벨의 총체적 거동을 이해하는데 집중되어야 한다. 구조의 강성 해석을 위한 최적의 모델은 설계 과정에서 응력 정보의 적절한 레벨을 제공한다. 보다 자세한 응력 해석을 하기 위해서 구조 모델은 응력 집중 또는 힘(또는 변위)분포 같은 자세한 국소 영역들을 가져야 한다. 본 연구는 자동차 차체 구조의 응력해석을 위한 설계 시 고려해야 할 사항들을 제시한 논문이다.

In the design of an automotive structural component, one of the more important tasks for a design engineer is to determine the life of the component and to ensure that the component will not fail prematurely. In order to accomplish this, a design engineer will first use simple section analysis to come up with a section shape in the concept design stage and use more advanced analysis for stress level. At this stage, the analysis should focus on understanding overall behavior in terms of load paths and gross stress levels. A model that is adequate for a stiffness analysis of the structure will usually provide an adequate level of stress information in the design process. To perform a detailed stress analysis, the structure models must have the detailed local areas such as stress concentrations or force(or displacement) distributions. This paper is to present the design considerations for the stress analysis of automotive structure.
