Tianming Automobile Company.

After several months of hard work, the airbag research and development project in charge of Zhou Jingming finally reached the stage of actual car testing, which was more than two months faster than Zhou Jingming expected.

In addition, Zhou Jingming also wants to re-discuss with Li Mingzhe on the standard of crash test, at this stage, there is no certain standard to follow in the domestic crash test, and many manufacturers will not even have a crash test.

Of course, looking at the world, there are very few car manufacturers that pay attention to crash tests at this stage. Crash tests were really valued by major car manufacturers, and it was not until the mid-nineties, especially in 1997, that the German NCAP crash test standards were proposed, so that crash tests became rule-based.

In addition, the crash tests taken at this stage are all frontal crash tests, and the side impact tests are not paid attention to by any country at all.

Because Tianming Automobile Company does not currently have a special crash laboratory, and this test is not a special crash test, mainly to verify the efficacy of airbags, so Zhou Jingming chose to build a new wall on a vacant land in the company for this crash test.

On the playground, the four new cars used for this test were neatly placed there, and Zhou Jingming was doing the final inspection of several test vehicles.

The four cars were divided into two groups, the Phoenix sedan and the Santana, with one in each group equipped with airbags, while the other was used as a control test without airbags.

In the seat of the driver's cab of the vehicle, the key "person" of the crash test is placed, ATD, which is often referred to as the crash test dummy, which Zhou Jingming specially bought from Germany. This kind of test dummy is based on a large number of corpse test research, the production materials on the body are special materials, plus the relevant sensor supporting facilities, the price of a dummy is worth a lot.

"The accelerometer is working fine. ”

"The displacement sensor is working fine. ”

……

With the end of Zhou Jingming's inspection process, the crash test has entered the final starting stage.

After doing all this, Zhou Jingming made an OK gesture to the rest of the staff, and the collision test officially began.

Zhou Jingming returned to Li Mingzhe's side, "Director Li, the results will come out soon, and you will know in a while how much it means to the driver whether to install airbags or not." ”

Li Mingzhe smiled and didn't speak, but his eyes looked at the playground, and while Zhou Jingming was speaking, the crash test had begun, and the four cars crashed directly into the wall used for the experiment at a speed of 50 km/h.

There was only a bang, and all four cars collided with the wall at the same time......

"Director Li, let's go over and take a look at the car. After the experiment, Zhou Jingming said to Li Mingzhe with a smile.

"Good. Li Mingzhe nodded, and followed Zhou Jingming to the car quickly.

All four cars, including the Phoenix sedan and the Santana, have been severely "disfigured" at the front, especially the Santana, where the cockpit and passenger compartment are severely deformed.

Zhou Jingming pointed to the Phoenix sedan without airbags, "Director Li, let's take a look at the dummy in this car first." ”

Following the direction pointed by Zhou Jingming, Li Mingzhe clearly saw that the dummy in the car, because of the violent collision just now, had already caused serious injuries, especially the head and chest, and the damage was even deeper.

"Look at this car again. Zhou Jingming didn't explain much, but pointed to another Phoenix car next to him and said, this car is equipped with airbags.

Without saying a word, Lee Ming-che walked to the other car.

At the moment of the collision, the airbag in the car was opened for the first time, because it was protected in time, the damage to the dummy, head and chest in this car was far lower than that of the car just now!

There is no need for Zhou Jingming to say anything at all, Li Mingzhe is already clear about the gap between the two.

"Director Li, let's take a look at the situation on Santana's side. Zhou Jingming looked at Li Mingzhe, who had a solemn face, and continued.

Next, Zhou Jingming took Li Mingzhe and others to take a look at the control test on Santana's side, like the Phoenix brand car, Santana with airbags, the damage to the dummy in the car is far lower than that without airbags!

The results are clear!

"I really didn't expect that the airbag would have such a big effect!" Xu Guanglu, who came with him, couldn't help but exclaim. Such a result was really unexpected by him.

"Theoretically, the use of airbags with seat belts, can reduce the probability of head injury by 25%, the probability of facial injury can be reduced by 80%, of course, at this stage, the car is equipped with only double airbags, if the driver's knee part is equipped with airbags, the protection of the driver will be more sufficient. ”

Zhou Jingming paused and continued, "Director Li, as early as 1984, the United States has added this item to the crash test standard, if our car is also equipped with airbags, it will definitely greatly reduce the casualties caused by traffic accidents." ”

"If the existing car is equipped with airbags, will the structure of the vehicle change much?" asked Lee Ming-che.

Zhou Jingming shook his head, "There is almost no conflict with the vehicle structure." ”

"If airbags are mandated nationwide next year, will you be able to keep up with the progress?" Mr. Lee continued.

At this stage, only Zhou Jingming's Tianming Automobile has mastered airbag technology in China.

"It will definitely be put into production next year, as for meeting the demand, with our current domestic car production, there must be no problem. Zhou Jingming paused, and his expression became more and more serious, "If the output of one of our companies cannot meet the market demand in the future, I am willing to take out the patent of airbag for free and share it in China." ”

Nils Boleyn, the inventor of the three-point seat belt, once provided this important invention that saved countless car drivers around the world for free and let the world use it for free.

At this point, Zhou Jingming is also willing to follow his example.

It's not about Our Lady, it's something that every car manufacturer should strive for.

"Okay, I have it in my mind. This time, when I returned to the mechanical engineering department, I worked with relevant departments to discuss the installation of airbags. Li Mingzhe nodded, the results of the experiment were in front of him, and he couldn't afford not to pay attention to it, not to mention, in order to promote this matter, Zhou Jingming was willing to take out the airbag patent for free, Li Mingzhe, as the person in charge of the competent department, what reason did he have not to promote this matter?

"Director Li, there is one more thing I want to tell you about, which is still about the crash test. ”

Li Mingzhe looked at Zhou Jingming suspiciously, "Is there any problem with the crash test?"

"What I just showed is just a frontal collision, and now I would like to ask Director Li to take a look at the side impact test. Zhou Jingming immediately replied.
