Post: Analysis of the material of anti-collision steel beam and “foam anti-collision beam”

Anti-collision steel beams are mostly made of high-strength steel, or their structural rigidity is enhanced through processes such as profiling and overlapping. This is because the anti-collision steel beam plays a key role in the transmission of force in a collision, and its hardness directly affects the force transmission effect.
However, some vehicles may not be equipped with traditional anti-collision steel beams, but foam fillers are installed in the corresponding positions, namely the so-called “foam anti-collision beams”. This design is mainly aimed at low-speed collisions, and has a certain buffering effect for minor or “gentle” level collisions, but it cannot cope with the real challenges of anti-collision steel beams as mentioned above.
In addition, the absence of rear anti-collision beams in Japanese cars is also a topic worthy of attention. This is not because the manufacturer is simple, but is related to the collision test standards at home and abroad. In China, there is currently no clear test standard for rear vehicle collisions, so the rear anti-collision beam is not a hard requirement. However, in Japan, due to the general high-speed and severe traffic accidents, the rear anti-collision beam has a relatively small protective effect on the occupants in the car, and coupled with Japan’s strict vehicle elimination regulations, the rear anti-collision beam is generally rare in Japanese cars.
