Abstract
In this study, the changes of displacement and stress are investigated by structural analysis according to the thickness of car body in case of overturn. In case of 5 mm thickness, the maximum displacement of 7.5024 mm at its right ceiling and the maximum equivalent stress of 113.69 MPa at the left lower part are occurred on the elapsed time of 2 second. In case of 10 mm thickness, the maximum displacement of 1.2557 mm at its right ceiling and the maximum equivalent stress of 15.134 MPa at the left lower part are occurred on the elapsed time of 2 second. In case of 15 mm thickness, the maximum displacement of 0.426067 mm at its right ceiling and the maximum equivalent stress of 4.4842 MPa at the left lower part are occurred on the elapsed time of 2 second. As stress and displacement are uniformly distributed according to time in this case, the design of car body can be stabilized.
