Front Bumper Crashworthiness Optimization

During a vehicles frontal crash, passengers jeopardize high acceleration and energy opposite to the mass follow direction of their bodies. This fact causes high injury to the passengers’ whole body; head, neck, chest, and legs. We started thinking of reducing this deceleration effect on passengers during the crash. This is because succeeding in reducing mass deceleration effect on the passengers’ bodies will lead to save passengers form serious injuries. Increasing the length of the front bumper crash boxes was a method to improve the impact energy absorption. However, increasing the geometry (the length of the crash box) of the front bumper assembly will lead to an endless chain of structure subassembly changes. Our methodology works on combing different types of materials and design optimization to control the crash deceleration while maintaining the geometry of the front bumper . This methodology works on absorbing or discharging the energy of the impact before the energy being transmitted in full to the passenger. On other word, we protect the passengers from the excessive energy which is generated by the crash before it reaches them. By having the control over these variables, our vehicles become safer to insure the safety for everyone. This methodology has a high potential to be applied to improve the side impact crash worthiness as well.
