What is the energy absorption block in a car's front bumper?

[DiKiara]

Car front bumper energy absorption block is designed to absorb and cushion the impact energy during frontal collisions. Materials used in vehicle energy absorption zones: Almost all vehicle body structures are composed of thin-walled metal components. During collisions, these thin-walled members subjected to strong impacts will undergo plastic deformation, which inherently accompanies the absorption of collision energy. Therefore, the crash performance design of vehicle structures largely depends on the crash performance design of thin-walled components. Principle and function of energy absorption blocks: The principle of energy absorption blocks is to utilize the deformation of the object itself to dissipate impact energy. Their function is to absorb the impact energy generated during collisions, protect passengers, and cushion the impact force.
