Are only Japanese cars capable of absorbing energy?
Many people think that only Japanese cars can absorb energy, but they don't know that the energy-absorbing design was invented by Mercedes-Benz engineers. At present, all family cars adopt energy-absorbing design. Believe it or not, the high rigidity of the cockpit, the collapse of the engine compartment, the sinking of the engine and the protection of the steering wheel shaft are the basic design ideas of all modern passenger cars. Energy absorption design is to deform and absorb kinetic energy in non-critical parts of the car body as much as possible to ensure the living space of the occupants in the car.
The safety of the vehicle depends on the energy absorption design and the strength of the body frame. As for whether the bumper is hard or not, whether the car shell is hard or not has little effect on the safety of the vehicle. For a simple example, if the subsidence area in front is harder than the A-pillar, the A-pillar will be damaged during high-speed collision.
There are still many people who take tanks as an example and say that if the energy absorption design is so good, why not use tanks? I'm really scared by your brain circuit. The scene used by tanks is the battlefield, and it is against all kinds of shells. Are you against the collision of two tanks? The tank does not use energy absorption because it uses something more advanced-reactive armor, which is completely different from passive energy absorption. It uses pre-stored chemical energy to counter the impact. This thing is not in the car. One is that the installation is too expensive, and the other is that it will explode and increase unsafe factors.
Who is more important, "guarantor" or "auto insurance"?
Some people still think that protecting cars is more important than protecting people when they collide. Then your life is not as valuable as a car, and there is a special evaluation system for vehicle losses. For example, the low-speed collision economy of China Insurance Research Institute measures the damage and maintenance cost of vehicles in low-speed collision. In this respect, Volkswagen brand models have performed well, please praise them. Japanese cars and luxury brands have this performance, which is related to the strength of the body skeleton, energy absorption design, the number of front sensors, whether equipped with LED headlights and so on.
However, in terms of medium and high-speed collision safety, Volkswagen models are very general. It can be said that they hit a car and overturned a car. From Magotan, Tiguan L to Passat, the bottom line has been refreshed again and again. So, should you say that the energy absorption design of Volkswagen models is good or general? When the strength of the collapse area in front of the locomotive is too high, the A-pillar may be directly damaged and the passenger compartment space will be squeezed. Passat is the most typical example.
Then, "why do people still believe in the energy absorption of Japanese cars?" The problem itself is problematic, because modern family cars have energy-absorbing designs. Instead of asking me why I believe in energy absorption, I would like to ask why some people believe that the thickness of iron sheet is safe, that the hammer knocks on the bumper door and stands, and that the heavy closing sound represents safety. The car safety engineer may be angry with you and vomit blood alive. Bella, the Mercedes-Benz engineer who invented the foldable body? Barney wants to know how he would feel if he knew it under the spring.
