The standard crash test actually consists of two parts, one is the frontal crash test just done by Zhou Jingming, which is also the mainstream crash test in the world, and the other is the side impact test.

The advent of side impact tests poses new challenges to vehicle safety. At this stage, the frontal collision test only puts forward requirements for the safety of the front of the vehicle, but in the event of a traffic accident, it is not always the head collision of two vehicles, and there are many cases where the car is hit from the side.

The traffic accident that Zhou Jingming encountered when he went home last time was that the vehicle hit the door from the side, causing serious deformation of the cockpit of the vehicle, and the driver was also killed on the spot.

And to some extent, hitting the vehicle from the side poses a greater threat to the life safety of the occupants than a frontal collision!

However, until now, the side impact test has not appeared in the crash test standards of any country, and even the United States, which has always attached great importance to crash tests, did not conduct the first side impact test until 1989.

"Side-impact test? Li Mingzhe was stunned for a moment, and asked suspiciously, this is the first time he has heard of such a test.

"When you say side collision, Xiao Zhou, do you mean a crash test from the side of the door of the vehicle?" Xu Guanglu understood it literally.

"That's right, as the factory director said, the crash test is done from the side of the vehicle. Zhou Jingming nodded and continued, "In the current crash test standards, there is indeed no provision for this experiment, but it is precisely because there is no reason why I specially proposed it to Director Li, because this experiment is also of great significance to the life safety of the occupants in the car." ”

"Then you talk about it carefully. Li Mingzhe frowned slightly, he was not very clear about the concept that Zhou Jingming said.

"Director Li, let's take a look at the difference between the side door of the Phoenix brand sedan produced by our Tianming Automobile Company and the Santana car. Zhou Jingming didn't answer in a hurry, but pointed to the cars and said.

Li Mingzhe's eyelids were raised, and he walked to the cars and looked at them seriously, while Xu Guanglu also followed and began to look at the car door.

A few minutes later, Lee Ming-che walked back and said, "I really don't see any obvious difference in the design of the doors between the two cars." ”

"Is there a difference in the thickness of the door?" said Xu Guanglu on the side, who was a little uncertain.

Zhou Jingming smiled, "Can the factory director explain it in detail?"

"Judging from the thickness of the door, the Phoenix sedan you produce is obviously wider and more protruding, and the position of the door occupying the space in the car is obviously larger than that of Santana, on the other hand, the door is just a thin piece of iron, or in other words, it is not as full as the door of the Phoenix car. Xu Guanglu thought about it seriously, and then replied.

When Lao Xu said this, it really meant a little bit. Lee Ming-che glanced at the car on the side again and said.

In fact, the reason why I designed the door of the Phoenix sedan into such a shape is not only in line with the overall shape of the body, but more importantly, I also added a crash beam structure to the door, in addition, the B-pillar and C-pillar of the body have also been strengthened and become thicker. Zhou Jingming gave his own explanation from a more professional point of view.

"What's the reason for your design, or what does it have to do with the side impact test you just mentioned?" Lee continued.

"Director Li, you can take a look at the comparative test in a while. Zhou Jingming replied with a smile, there is nothing more intuitive than looking at the experimental comparison with his own eyes.

Next, Zhou Jingming readjusted the four cars that had just completed the frontal crash test, although the front of the body has been seriously damaged, but it does not prevent the next test, it is too expensive to get a new product car, Zhou Jingming is reluctant......

After all the preparations, the car crashed into another car at 50 km/h, only this time with the front of one car, into the side of the other.

There was another loud bang, and the cars of both models crashed into their respective targets at the same time.

After the dust cleared, Zhou Jingming looked at Li Mingzhe and Xu Guanglu again, "Director Li, factory director, now take a look at the results of the experiment, you will know why I asked for a side impact, and why I designed the car like that." ”

Li Mingzhe and Xu Guanglu stepped forward to take a look, and they were immediately stunned, compared with the previous frontal collision test, this time the side impact test, the results are more obvious!

Santana's door had been completely twisted and deformed after such a violent impact, and not only that, but the cockpit and the passenger compartment were completely deformed, and it was hard to imagine what a tragic scene it would have been if there were real people sitting in it at this time.

However, in comparison, the deformation of the cockpit and the passenger compartment of the Phoenix sedan, which also hit at a speed of 50 kilometers per hour, is much smaller, and the escape probability of the occupants is also greatly increased.

"Director Li, do you know now why the side impact test is so important?" Zhou Jingming stood aside, and the traffic accident he saw that day appeared in front of him, "After the door is equipped with an anti-collision beam, its strength has been greatly improved, and the B-pillar and C-pillar can also play a buffering role, as long as the cockpit and the passenger compartment can be effectively protected, the people in the car have a great chance of escaping, in addition, the door is designed like this, which is also conducive to the installation of side airbags, under double protection, the casualty rate will be reduced!"

Airbags can be installed not only on the front of the vehicle, but also on the sides.

Lee Ming-che became silent, China's automobile industry has just started, many safety regulations are not very perfect, even the crash test, is borrowed from European and American countries, not very perfect, let alone any side impact.

"Xiao Zhou, has the side impact test you just mentioned been implemented in these automobile powerhouses in Europe and the United States?" Li Mingzhe's eyes looked at the two cars that were hit again, and his voice became serious.

"Not yet. Zhou Jingming shook his head, "But as far as I know, the United States will soon start to implement such standards, and at the latest next year, such regulations will be promulgated there." ”

"How much do you know about the standards of crash tests, including frontal and side impacts, or what needs to be improved in China's current crash test standards?" Lee Ming-che continued.

"If Director Li wants to revise the standards for crash tests, I can really help, but these regulations are too strict and will have a certain impact on the development of China's automobile industry. ”

If it is really implemented according to the crash test standards issued by Germany in 1997, then many cars, including Santana and Hongqi sedans, will have to reconsider the exterior design.

"No matter how much we develop, we can't gamble with the lives and safety of the people. Lee Ming-che said categorically.
