Abstract:

This study aims to evaluate the effectiveness of using Vibration Damper Foam (VDF) as a vibration damping component in electric car batteries. The need for vehicles that are lightweight but resistant to vibrations due to poor road conditions is increasingly important, given the potential damage to battery cells that can cause failures, such as explosions or fires. The relevance of this research is increasing along with the global growth of electric vehicles, including in Indonesia. The research method involves numerical simulations with variations in the thickness of the aluminum foam sandwich, namely 10 mm, 15 mm, and 20 mm. Data from the simulations were then validated through vibration tests in the laboratory to compare their agreement with experimental data. Initial simulations were performed without using aluminum foam to determine the baseline values, and then compared with simulations using foam. The results showed that without aluminum foam, the acceleration reached 8409.86 m/s2, displacement 0.0122 m, and velocity 10.36 m/s. Meanwhile, with the use of 20 mm aluminum foam, the acceleration, displacement, and velocity were reduced to 1739.96 m/s2, 0.0041 m, and 3.00 m/s, respectively. The conclusion of this study is that the addition of sandwich aluminum foam significantly reduces vibration in electric car batteries, thereby improving the safety and reliability of electric vehicles.
