Abstract

In this study, the torsional rigidity and durability of the stabilizer models with the hollow axis of light and large sized cars were compared and investigated each other. Model 1 was applied with the moment more than three times as much as model 2, but the maximum deformation of model 1 was seen to be about 2.6 times larger than that of model 2. Commonly, models 1 and 2 are seen to get the most stress at the neck of stabilizer bar link. Also, the maximum stress of model 1 was about 2.9 times larger than that of model 2. Model 1 at large car showed more than 20 times more deformed energy than model 2 at small car. Overall, it could be examined that the deformation energy of the bracket part on the side where the moment fixing the stabilizer bar was applied was greater than that of the stabilizer. It is thought that the analysis results in this study can be helped at the design of its convergent research as a durable component of the stabilizer at a light or large sized car.

본 연구에서는 경차와 대형차의 중공축을 가진 스테빌라이저 모델들의 비틀림 강성과 내구성을 해석하여 서로 비교 및 검토하였다. Model 1이 가해진 모우멘트가 Model 2에 비하여 3배 이상이었지만 최대변형량은 2.6배 정도로 크게 나타났다. Model 1, Model 2 공히, 스테빌라이저 바 링크 목 부분에서 가장 많은 응력을 받는 것으로 보인다. 또한 Model 1의 최대응력은 Model 2보다 2.9배 정도로 크게 나타났다. 대형차에서의 Model 1이 소형차에서의 Model 2 보다 약 20배 이상의 변형 에너지를 보였다. 전반적으로 스테빌라이저의 변형 에너지보다 스테빌라이저 바를 고정해주는 모멘트를 가한 쪽의 브라켓 부분의 값이 큰 것을 확인할 수 있었다. 그리고 본 연구에서의 해석 결과들은 경차나 대형차에서의 스테빌라이저의 내구성이 있는 부품으로서 그 융합연구 설계에 도움이 될 수 있다고 사료된다.
