Abstract

In this study, the structural and fatigue analyses were carried out according to the configuration of rear wheel suspension of torsion beam. Three types of models similar to the actual torsional beam suspension are analyzed and we will find out which one is best on strength. The models of torsion beam suspension were designed in three types of models A, B and C through CATIA program and the results of structural and fatigue analyses were obtained by using the ANSYS program. We will confirm which model is better structurally than other models. According to the analysis results, the deformation happens to be the largest in the middle, and model B has the least deformation compared to model A and C. Similarly, model B is shown to have the smallest result at equivalent stress. So, model B is judged to be the best in terms of its strength, and it is thought to be the most efficient to converge into art design at the suspension design with a torsion beam of rear wheel.

본 연구에서는 토션빔 후륜 서스펜션의 형상에 따른 구조 및 피로 해석을 하였다. 실제 토션빔 서스펜션의 형상과 비슷한 3종류의 모델들을 해석하여 어떤 것이 강도상에서 가장 좋은 지를 알아본다. 토션빔 서스펜션의 모델들은 CATIA프로그램을 통하여 Model A, B, C 3종류로 설계하였고 ANSYS 프로그램을 이용하여 구조 및 피로 해석의 결과들을 얻었으며, 어떤 Model이 다른 모델에 비해 더 나은 구조적 형상인지 확인한다. 해석 결과에 따르면 변형은 주로 가운데 부분에서 가장 크게 발생하며 Total deformation의 경우 Model B가 model A, C 에 비하여 변형이 가장 적었다. 마찬가지로 Equivalent stress에서도 Model B가 가장 작은 값이 나타난 것으로 보아 Model B가 가장 강도적인 면에서 가장 좋은 것으로 판단되었으며, 후륜 토션빔 서스펜션 설계 시에 디자인 예술과 융합하는 것이 가장 효율적이라고 사료된다.
