Why the speed of car crash test is not fast
Regarding the driving speed of the car crash safety test, it is almost impossible to find a car crash test at a speed of 100K kilometers per hour. The tests in China, Germany, Japan, the United States, Europe, Australia and other countries that can be found on the Internet are almost 50 to 60 kilometers. , Why not test the higher speed? First of all, the principle of the car crash test is to simulate the state of the actual traffic accident. Generally, when a collision occurs, the car does not hit the target at full speed. There is a braking action. The 2012 version of the Chinese C-NCAP crash test claims to have adopted almost the same crash standards as the European safety crash: a frontal collision with a vehicle speed of 50km/h and a rigid fixed barrier with a 100% overlap rate, and a vehicle speed of 64km/h. A frontal offset collision with a deformable barrier with a 40% overlap rate, a side collision with a vehicle at a speed of 50km/h of a deformable movable barrier, and a neck protection test project after a low-speed collision. Secondly, the energy at the time of a collision is proportional to the square of the vehicle speed. Even if the car with the best safety of the five-star test encounters a higher speed collision, it will be vulnerable. It's almost pointless to test a higher-speed collision. A fool will crash a car at full force, and the car is not built for collision. At higher speeds, all kinds of cars crashed into a pile without distinction. In fact, with the advancement of design level, technology and materials, the speed of collision test is gradually increasing, and the test standards are becoming more and more demanding.
