초록

Prior to the design and production stages of the center pillar, the structural analysis must be carried out at the concept stage. Commercial softwares for the structural analysis provide benefits such as performance prediction and deformation. In this study, the structural analysis using SolidWorks was performed to investigate the stress and displacement characteristics of the center pillar for two types of collision positions and velocities. As the impact velocity increased, the maximum equivalent stress and displacement of the center pillar were larger. In the case of passenger cars, the equivalent stress and displacement according to the velocity change increased by about 133% and 116% at 16.5m/s , based on 5.5m/s . Also, the equivalent stress and displacement in the SUV car increased by about 119% and 378%, respectively
