A bumper beam is a device designed to mitigate impact forces on a vehicle. Its ends are connected to low-speed energy absorption boxes with lower yield strength and are bolted to the vehicle's frame rails.
The low-speed energy absorption boxes effectively absorb collision energy during low-speed impacts, thereby minimizing damage to the vehicle's frame rails from the impact force, thus providing protection for the vehicle. To better fulfill its protective function, the bumper beam also requires optimized design.
