Özet

Vehicle safety has become one of the primary focus areas of the automotive industry in line with global regulations and consumer expectations. Side impact performance is a critical parameter that directly affects occupant safety, and verification studies in this field can significantly influence both prototype costs and overall development time. Therefore, performing virtual validation analyses through Computer-Aided Engineering (CAE) methods prior to physical testing has great importance. In this study, a CAE analysis of the static side impact (front door intrusion) test defined by the FMVSS214s standard was conducted on a light commercial vehicle. The aim of the study is to evaluate the compliance of the vehicle’s structural strength with regulatory requirements, to investigate deformation behaviors in critical regions, and to obtain engineering insights for potential design improvements. The analyses were performed using the LS-DYNA finite element solver. The vehicle model consists of Bodyin-White (BIW) and door panel sub-models. Based on the loading conditions specified in the FMVSS214s standard, the deformation response of the body structure under the applied force on the door surface was examined. CAE results were evaluated through the average force– displacement curve in accordance with the limit values defined in the standard. High deformation levels were observed in the A and B pillars, door panel, and beam regions; however, no separation occurred at the latch or hinge connections. The obtained results demonstrated that the regulatory requirements were successfully met.
