Until we left the test lot and entered the venue specially built by emp for this collision test, everyone still had not recovered from the shock just now. What was still ringing in our minds was the fiery red figure that was rushing and the sound of the engine that made people feel excited.

Even if I was unwilling to accept it, I had to admit that the emp in front of me already had the strength that made them afraid of.

However, when Cen Qing looked at Bai Ningyuan, he looked a little more thoughtful and interested. Although he had known for a long time that the young man in front of him was not simple and unusual, there were some things that he could have a real understanding of.

Zhang Peisheng followed the team and never spoke from beginning to end, as if he was invited to participate in the emp test this time, but he just brought his eyes over.

Everyone climbed up the observation platform built around. This platform, which was slightly more than one meter higher than the on-site test site, could better see the situation of this test.

On the wide field not far away in front of them, a white concept.f was quietly staying there, waiting for him to break into pieces that were about to begin.

In addition to cars, what attracted everyone's attention was the long acceleration track in the venue, various devices used for testing, and the high-speed cameras visited around. The dense appearance made people shocked.

How much does such a collision cost?

But it's just a concept car, as for putting such great efforts!

When I saw this, I couldn't help but turn my eyes to the young man not far away. Seeing him calmly chatting and laughing among the middle-aged and elderly men, it was really hard to believe.

"There are four tests to be conducted today, namely the 25% overlapping collision test on the front, the 100% overlapping rigid barrier wall on the front, the collision test on the side deformable mobile barrier wall, and the pedestrian protection & children's collision protection test!" Bai Ningyuan introduced to everyone present through the gap between the staff's preparations before the test.

After hearing Bai Ningyuan's words, Cen Qing and others were fine, but they didn't know much about it. Although the auto industry like Li Shufu and Yin Tongyue had not tested their products on the contrary and were not paying much attention to it, it does not mean that they had not heard of the relevant situation. It is just that the projects Bai Ningyuan mentioned seem to be different from those they heard of.

The collision test of this side can be deformed and moving obstacle wall, and they know that this pedestrian protection and children's collision protection can also be seen by just listening to the name. It goes without saying that the 100% overlapping rigid obstacle wall on the front is naturally a must-have, whether in Europe and the United States, or in the next door to Japan, this is indispensable in its collision test.

But what the hell is this 25% overlap collision test? Why have you never heard of it?

"Mr. Bai, I have basically heard of other projects. What is this 25% overlapping collision test? Is it actually meaningful?" At this time, the reporters on those websites naturally developed the advantages of being diligent in learning and asking questions. If they don't understand, they asked Bai Ningyuan directly.

"This test is to accelerate the test vehicle to a speed of 64km/h, and then hit a rigid barrier with an overlapping area in front that is equivalent to 25% of the width of the vehicle body!" Bai Ningyuan replied with a smile, "The obstacles that collide with 100% full width do not have an energy-absorbing structure, and all the energy of the collision is absorbed by the vehicle body, so this test tests the structural rigidity of the vehicle body and the design balance of the energy-absorbing zone. If the design of the energy-absorbing zone is unbalanced or the structural rigidity is unreasonable, the parts of the vehicle body that absorbs a lot of energy will collapse in advance."

After a pause, seeing everyone's eyes focused on themselves, Bai Ningyuan continued to popularize the people: "But we know that in daily driving, such a 100% head-on collision is difficult to happen, because the driver's subconscious avoidance behavior often results in a collision on part of the car body. In this case, due to the bias collision, the car body is subjected to uneven stress, and the car body will twist and deform. At the same time, the collision occurs on one side of the longitudinal axis of the car body

, it will generate torsional torque, which will cause greater harm to the deformation of the vehicle body and the passengers. Therefore, this test is set up in a simulation of such a scenario. It conducts sufficient testing and evaluation on the body structure design, the rigidity of the body material, the protection of the passenger compartment, whether the side air curtain and side airbag plays a corresponding protective role, whether the a-pillar is deformed, whether the intrusion of the passenger compartment exceeds the standard, and whether the escape space is sufficient, so that the safety of a car can be seen more clearly. It is not an exaggeration to call it the most stringent test! "

After hearing Bai Ningyuan's introduction, the scene suddenly became a little silent. The people in the car circle all opened their eyes wide and looked at Bai Ningyuan with disbelief, with a look of unsure in their eyes.

No one present was an amateur. After hearing the rigorous content of this project test, he couldn't help but feel his throat dry. Just thinking about this test felt terrifying.

If it is a 100% head-on collision, there is still a way to take advantage of the situation. However, in this 25% small angle collision, all tricks are useless, which is the most test of the strength of a car's body skeleton. Not to mention anything else, none of the car companies present dares to take out their products from home to do such a test, because they don't know what the final result will be.

For a long time, under the strong publicity and brainwashing of some car companies, domestic users always have a misunderstanding when choosing a car, that is, look at the steel plate. The thicker the steel plate, the safer the car is. This concept is still popular even before Bai Ningyuan was reborn.

But in fact, if the car is compared to humans, the body structure is human bones, and the steel plate outside is human skin. When a collision occurs, the role the steel plate can play is simply tiny. More importantly, the thicker the steel plate, the weight of the car body is invisibly increased and a lot of fearless fuel consumption is increased.

The frame that really plays a decisive role in safety is the frame. This type of component is not ulterior motives, the stronger the better, and of course it is not the weaker the better. The basic requirements for safety-related components are: when it needs to be strong, it will be strong, and when it needs to be weak, it will be weak, and the combination of hardness and softness is the king!

Bai Ningyuan's courage to challenge this rigorous test invisibly demonstrates his strong confidence in his products.

Just when everyone was still thinking differently, a sound of the motor suddenly rang, attracting them to turn their eyes to the venue. Where, the white car pulled by the motor accelerated rapidly and rushed forward towards the obstacle in front of them...

The second update today!

The author went to another place to accompany the bed, automatically posted chapters, and kept updating! The performance of last month was not good, and it was probably just a barely living. Now the new January has begun. I hope everyone can support it enthusiastically, subscribe and give more rewards! Especially in the past few days when I was away...
Chapter completed!
