[YesAuto 车台勐料] Nowadays, when someone in China does something meaningless and boring, people will say “Thank Yuan Longping”, which means that because of the father of rice, those talents will make such an act of eating and doing nothing. There is no Yuan Longping abroad, but there are more people who “have nothing to do”. Recently, someone in Germany conducted a collision test on two Lego models…
Doing a crash test on a Lego model sounds like a spoof of boring netizens, but it is not the case. The test was conducted by one of the most professional car testing institutions on the planet, the German ADAC (All-German Automobile Club).
The protagonist of this test comes from the Lego mechanics group. One is the flagship Bugatti Chiron model of the automobile category, which is composed of 3599 parts; the other is the discontinued Porsche 911 GT3 RS model, which has 2704 Lego particles on its body.
Although it is a model collision, ADAC has carried out the whole process with the high standard of real collision: On the test track of the Landsberg Technology Center, 8 cameras with different angles record every detail of the collision at a speed of 1000 frames per second, in order to ensure high speed During the exposure of the photography, 300 1000W halogen bulbs were lit on site.
The staff placed the blue Bugatti Chiron model laterally at the end of the test track. On the track, the Porsche 911 GT3 RS model “drove” at a speed of 60km/h and hit the side door of Bugatti. The result of the collision is self-explanatory, the vehicle The parts splattered away, and Bugatti was smashed into two pieces. The front part of the Porsche was also torn to pieces. Both cars failed to drop the “corpse.”
With this “explosive” result, the crash test was completed, so why did the Germans do this test? Is it just to satisfy the inner desire of destruction? Really not. The initiator of this test is the German technical magazine C't. The purpose of this test is to evaluate the results of computer simulation calculations.
First, they conducted a simulated collision test on this Lego collision through a computer, and then performed an actual collision in a real environment to check whether the simulation test result can replace the actual collision. The final result is not optimistic (for the computer), because the damage caused by the actual collision is much greater than that of the computer simulation, so C't magazine concluded that computer simulation can greatly reduce the research and development costs, but it is not completely at present. Replace the actual crash test. (Wang Meng, Home of Wenzhou Automobile)
