초록

Prior to the experimental and production stages of the center pillar, a structural analysis must be carried out at the design stage. The commercial software for the structural analysis at the design stage provides benefits such as cost-effective and time economy. In this study, the structural analysis was performed to investigate the stress and displacement characteristics of the center pillar for five types of the applied loads using SolidWorks. The equivalent stress was relatively larger on the outside plate than the inside plate. The maximum equivalent stress according to the change of the applied loads increased linearly in the range of 47~181%. The deformation was larger at the upper end of the center pillar, and the maximum displacement was linearly increased in the range of 35~187%. The analysis results of the center pillar according to the applied loads show that the location and distribution of the maximum stress and displacement of the center pillar can be predicted.
