Is car energy absorption a false proposition?

I don’t know when, when it comes to absorbing energy, everyone thinks of Japanese. What's more, it is a false proposition to think that energy absorption is a false proposition. What is energy absorption? Is energy absorption a false proposition? First of all, energy absorption is definitely not a false proposition. The concept of energy absorption was first proposed by the German Bela Barenyi, known as the "Father of Automobile Safety". Modern family cars all have energy-absorbing structures. To put it simply, the engine compartment is sacrificed to protect the safety of the passenger compartment. Therefore, to judge whether a car's energy absorption is effective, one cannot just look at the amount of deformation after a collision. It depends on whether the passenger compartment is complete. Whether the occupants are safe. The most common energy-absorbing structure is the energy-absorbing box. The energy-absorbing box plastically deforms during a collision, and the vehicle can effectively absorb collision energy during low-speed collisions, minimizing damage to the body longitudinal beams. Energy-absorbing box made of the same material. The thicker the wall of the energy-absorbing box, the smaller the energy absorbed, but the greater the safety distance. The thinner the wall of the energy-absorbing box, the greater the energy absorbed, but the smaller the safety distance. So what would happen if the car body did not have an energy-absorbing mechanism? The engine compartment did not collapse, and the driver and passengers were quickly squeezed forward by the inertia at the moment of collision. It is easy to damage the cervical spine or even cause death. I believe everyone has a deep understanding that the quality and safety of products under the same brand are uneven at present. So you can't deny a brand or become a fan of a certain brand because of a certain car. A popular B-class car from a German brand has a rear anti-collision beam that can almost be bent by hand... A Japanese brand actually tore the B-pillar during a crash test. Therefore, there is no need for us consumers to argue with each other. Why don’t some large cars have energy-absorbing structures? First of all, the passenger compartment of large cars is relatively high. The risk to the occupants themselves is relatively small. Secondly, some heavy trucks also have energy-absorbing mechanisms, which use cockpit displacement to ensure the safety of the occupants. Another point is that large vehicles have large tonnage and have an absolute advantage in collisions. It is often said that you don’t buy a car to crash. But there is this risk when going on the road. Although the probability is small, we can reduce the losses caused by this risk as much as possible.
