| 초록 |
Most electric vehicles manufactured these days include battery packs and powertrain parts mounted at the bottom near the rear axle or rear wheel. In this study, we analyzed and identified the main factors for determining stone chipping deformation, which causes the unwanted destruction of underbody parts while driving electric vehicles. By analyzing the average level on the stone chipping phenomena and signal-to-noise ratio, the influence of external impact factors(e.g., velocity, mass, shape, and material property) on stone chipping deformation was confirmed based on the Taguchi method. Based on the analysis of the stone chipping impact diagram, we can propose a design guideline for the underbody parts in order to reduce the development cost and time. |
