다국어 초록 (Multilingual Abstract)

This study aims to mitigate vibrations generated by the seats of autonomous vehicles. Vibration measurements were acquired through experiments, and an analytical model was calibrated using beam elements to accommodate variations in constraints. To assess the efficacy of vibration reduction, a two-degree-of-freedom model was employed to characterize the dynamic damper. Sensitivity analysis of vibration magnitude indicated a significant reduction achievable with the dynamic damper. Configured as a 3D finite element model, the dynamic damper’s design factors were determined by mass and Young’s modulus. Results from the response surface methodology revealed an approximate 6 % margin of error in optimal parameters. Consequently, it was demonstrated that the vibration amplitude of the sheet could be reduced by approximately 50 %, and optimal parameters corresponding to this reduction were identified.
