낙하 충격, 압축 및 진동 하중 하에서 전기자동차 배터리팩 케이스의 구조적 신뢰성에 대한 유한요소해석
Finite Element Analysis of the Structural Reliability of an Electric Vehicle Battery Pack Case under Drop Impact, Compression, and Vibration Loads
This study presents the results of compression, drop impact, and vibration durability analyses conducted to evaluate the mechanical reliability of Battery Pack Cases (BPCs) in electric vehicle (EV) systems. BPCs are essential structural components that must endure compressive loads, impact forces, and vibrational fatigue. Finite Element Analysis (FEA) was applied to a representative BPC model to assess deformation, impact resistance, and vibration endurance. The results indicate that the BPC maintained integrity within yield strength limits under compressive loading and effectively absorbed energy under drop impact. Furthermore, Power Spectral Density (PSD) analysis identified stress concentration regions, providing insights for structural optimization. Overall, the findings support the development of lightweight and reliable BPC designs for advanced EV applications.
