Coquettish Rebirth

What hidden danger did Jia Hongjian think of?That was a rule that was summed up within the industry when Japan was developing automobiles—the ratio of GDP per capita to the selling price of automobiles should be kept above 1:4 as much as possible.That is to say, the wealth a person can create in one year—not the money earned—should allow him to buy the most popular car on the market for 4 more years!When Japan started the national car plan in 1955, the per capita gdp of ri people was lower than that of China in 95, only 300 US dollars. At that time, the requirement in the national car plan was to develop a car with a price of 360 yuan and a cost of about 1 yuan.

If this is replaced by China, that is, when the per capita GDP in 95 was 4044 RMB, the most popular car on the market that can be developed should be priced below 1.6 yuan, preferably around 8000 yuan!And the cost is preferably only 6000 yuan!Is this Nima a car?It's only a little more expensive than a motorcycle, okay?So even if it is due to the factors of the times, if you want to improve, then according to a family with two employees, the average annual gdp of the two people has reached 8000 yuan, then the price of the car is reasonable at less than 3.2 yuan, preferably around 1.6 yuan!

The price of RMB 3.2 sounds similar to the car priced at RMB 3 or RMB 68 that Jia Hongjian said. How could this be a hidden danger?This hidden danger lies in the fact that the Japanese government made such a request back then, so to a certain extent, it stimulated the Japanese automakers to start "cutting corners"!Although in theory, Japanese car dealers rarely cut corners, they just stick to the minimum requirements of the local country very frugally.For example, for a certain device, the local country stipulates that a certain part must be more than 80 mm. Just now, American products and European products may use about 90 mm, which leaves enough margin, while Chinese domestic products have technical problems.In many cases, it will be 100 or even 70, so as to ensure the margin, but for Japanese goods, he may be very bold to control it at 69 or even 68, [-]!This effect is to significantly reduce costs.But it increases the safety risk - because the safety margin is gone!It may be slightly more than a little bit of load, and the Japanese goods will kneel directly!

This is not Jia Hongjian's bragging. The Japanese cars of the later generations basically followed this idea-in order to save fuel, they made the body thinner, and even sat on the sheet metal to the point where it could be depressed by hand.Some people say that this is actually a safety design, which is to use flexibility to resolve the impact force, so as to ensure the safety of the human body.good.Even if this is true, how come the high-end Infiniti cars of the Japanese series don't look like the Japanese style at all, but are hard to die for?I didn't even feel scared when I hit an American car. In the end, the American car was shrunk, and the Japanese Infiniti just broke the paint and left?

Even if you don't talk about this, let's talk about the fuel economy of RI cars.In addition to saving fuel on the steel plate, the fuel-saving part reduces the weight of the vehicle. What Jia Hongjian most dislikes about the RI series is to reduce the width of the tires!The wider the tire width, the greater the tire resistance and the more fuel consumption.For example, many compact models worth tens of thousands in 2012, American cars and European cars all use tires with a width of 10 or 215, which leads to high fuel consumption, but the deflection of the car body is small when turning.And how crazy is the Japanese system?Almost the same price, using 205 tires or even 195 tires!Well, in this way, the fuel consumption is reduced, but the body tilt increases when turning!

Therefore, what Jia Hongjian is worried about is whether the price will be inadvertent in the end because of the price limit.Instead, let Huaxia Hi-Tech's cars become like Japanese cars, cutting corners and making them soft like puffs?

Just when Jia Hongjian was slightly worried, the Great God Guo seemed to see that Jia Hongjian was not very happy, and he asked with a smile: "What's the matter, Mr. Jia is not satisfied with me bringing students here alone. "No no. I was thinking, because we have set a price limit, I am afraid that the safety will not be very good because of the lack of steel used..."

"Haha...I didn't expect Mr. Jia to know a lot. Yes, there were such problems in the 50s, but now it's the 90s. We can use all-plastic car shells, or even all-plastic cars. Use fiberglass Add carbon fiber, so that the ductility and hardness can catch up with or exceed steel, but the weight is reduced by half. In fact, when you said before that you want a 0.67l displacement engine and a speed of 100 kilometers per hour, I have already considered using fiberglass car shell It's already..." Mr. Guo said with a smile, as if this kind of all-plastic car is already commonplace in this era.This kind of scene made Jia Hongjian's thinking confused for a while—was he reborn to the past, or traveled to the future?Why haven't I heard that in the future, the outer shell of a car or even the whole car will be made of plastic or fiberglass?

Seeing Jia Hongjian's surprised expression, Mr. Guo smiled and said: "In fact, in the 80s, the concept of all-plastic cars first emerged in our country, and even the all-plastic car shell was the first to be made in our country. At that time, the British were surprised, and they came here to investigate. Actually, to put it bluntly, in terms of foreign aviation concepts, it is composite materials. In the late 60s, composite materials were already used in cabin doors and other places abroad. Later, the horizontal tail of f14 fighter jets used boron fiber reinforced epoxy resin composite materials, and later fa-18 used composite materials on the wings and fuselage. Even civil aircraft, in the 80s In the mid-term, components with less stress, such as elevators, rudders, flaperons, etc., began to be made of composite materials. It can be used in aircraft, but is it not trivial to use in cars? The biggest problem is that composite materials are often not suitable for industrial production, such as Carbon fiber FRP often needs to be hand-laid. However, the price of hand-laid is not expensive. I estimated that if you make a mini car according to your requirements, the cost of a full set of car shells is about 8000 yuan! If you make enough, we will cost It can also be lowered to 7000 or even 6000. If some funds can be invested in the development of semi-automatic or automatic manufacturing, it should not be a problem to reduce it to 5000 or even 4000..."

Wow... so the technology in 95 has advanced so much? When Jia Hongjian was still young in the 80s, he really didn't know that the Chinese people had already started thinking about making glass fiber reinforced plastic car shells, and even alarmed foreigners!However, it is estimated that composite materials such as glass fiber reinforced plastics could only be hand-pasted at that time, and there was no way to industrialize large-scale machine production, so the world has been slightly stagnant?However, if it is true as Mr. Guo said, the performance of carbon fiber glass fiber reinforced plastic or composite materials is not inferior to steel, and it is easy to form, plus it is light in weight, then his plan for the national car may not be successful It can be perfectly realized!Maybe the price can even be lowered to a little over 2!

But the only problem is that this production line is difficult to get.If the production line is easy to get, it is estimated that foreigners have already set it up these years.The production line is not good and the result is low output.If the steel plate is used to make the car shell, as long as the mold and process pass the standard, then a curved roof will come out after pressing it.And if this kind of composite material is made, the board can't be made every second!In this way, the output is limited, the output is limited, and the sales that can be sold are limited.

"Okay, you, the boss, don't need to pay so much attention to specific technical issues. You can find experts for public relations. Later, I will ask Haitao to go to the Ministry of Metallurgical Industry and their Science and Technology Department. They specialize in research and development. With all kinds of new technologies and processes, it should be no problem to ask a few of their experts to help design a process or something, and they also manage metallurgical and military matters. They have a lot of black technology hidden there. It’s not that you can’t use them if you don’t have a confidentiality level…”

Listening to Mr. Guo's words, Jia Hongjian really got a little confused—god, ask the top experts in the metallurgical industry of the Republic to help?Even the kind of power to study composite materials for military aircraft?Find them to study how to design a glass fiber reinforced plastic shell production line for a small broken car priced at 3 to [-] yuan?How does this feel like a cannon hitting a mosquito, how does it feel like "pull Jordan to help my class play an intramural basketball league"?It seems a bit too much?

At this time, the old man seemed to see Jia Hongjian's thoughts, he grinned and patted Jia Hongjian's shoulder, "What's the matter, didn't you just say you were going crazy? Didn't you mean that you were very ambitious, didn't you?" Do you want to be China's Toyota? Toyota has the support of the Japanese government, so our country can't support us? This is just the beginning of madness, why don't you take the lead? Haha, boy, this is the beginning!"

ha?This is the beginning?How much exaggeration do you have to do after that?Wouldn't it be possible to find someone who is designing J-10 fighter jets or designing missiles and satellites in China to help design the shape and internal structure of a 3 to [-] yuan small broken car?Wouldn't it be said that this little broken car should be pulled into the air hole in the military base to see the aerodynamic force and air resistance?After the prototype car is produced, won't the ace test pilot of the army come to test this little broken car?Wouldn't it be the same as the army tank test, from the subtropical rainforest of the South China Sea Island to the extreme cold of the Northeast, from the dampness of the land of fish and rice to the Gobi Desert in the Northwest, and finally go to the Qinghai-Tibet Plateau to try its performance?This is really just a small car for civilian use. Doesn’t it need to test the performance and reliability of various extreme environments according to military supplies?
