Side impact collisions pose significant risks to passenger safety due to limited deformation space. This study investigates using the 7075-T6 aluminum alloy in vehicle side impact beams to enhance safety. The 7075-T6 alloy's higher specific strength compared to the commonly used 6061 alloy was tested using finite element models and Federal Motor Vehicle Safety Standards. Results showed that the 7075-T6 alloy beam exerted a force three times greater than the 6061 alloy beam, demonstrating superior intrusion resistance and potential for reduced occupant injuries. These findings highlight the promise of 7075-T6 alloy in improving vehicle safety standards and suggest its potential application in future automotive safety designs.
