유한요소모델의 마찰계수가 충돌해석결과에 미치는 영향 연구 = A Study on the Effect of Friction Coefficient in Vehicle FE Model for Virtual Crash Test Results

다국어 초록 (Multilingual Abstract)

The essential process of automobile crash testing, which evaluates the collision safety and occupant protection performance of vehicles, is costly. As a result, virtual crash testing, which can substitute or complement real-world testing, is being researched and applied as an effective alternative. As the application scope of virtual crash testing expands, research is actively being conducted to verify the reliability of the results obtained from virtual crash tests and their similarity to real-world crash tests. In this study, the effect of changing the coefficient of friction between the passenger and vehicle contact parts during high-speed collisions in a specific range of friction coefficients was quantitatively analyzed. It was found that the impact of the friction coefficient varied depending on the analysis model, and in the crash analysis, there were differences in the maximum reaction force and the shape of the reaction force curve over time. Therefore, it is necessary to examine the range of friction coefficients applicable to virtual crash testing.
