Rebirth 99 to become a car giant.

Chapter 272 As long as there are enough tools and people, a new car can be awesome

How to keep the topic hot on the Internet, Cao Yang definitely has the right to speak more than anyone else.

If Xingchen Auto wants to take the high-end route, it definitely needs various exposures.

So there is no harm in publishing some news about your own family every now and then.

Whether Xingchen 1 is benchmarking against BMW 730, or the gearbox is going to use 8AT, although not all of these news were released by Cao Yang on his own initiative.

But after it was exposed on the Internet, he did not arrange for anyone to suppress it.

Even Autohome will follow suit and expose some further news.

In this way, Xingchen Automobile is remembered by many netizens.

However, Cao Yang himself was very busy during this time.

The company has recruited a bunch of tool people, and naturally they have to make some achievements in the development of Xingchen 1.

In the design departments of powertrain, chassis, body, interior decoration, exterior decoration, electronic appliances, etc., Cao Yang personally participated in the development of some parts.

"Mr. Cao, if the new car must use an air suspension, it is best to use a double-wishbone structure for the front sub-frame, and a five-link independent suspension for the rear sub-frame."

"In this case, we can adapt to the needs of the air suspension."

"Otherwise, it is like a McPherson structure. Since the spring damping strut is rigidly connected to the steering knuckle, the change in the length of the front suspension spring will directly lead to a change in the camber angle of the front wheel."

"Because the trajectory drawn by the lower arm is a circular arc, the change of the front wheel inclination angle with the length of the spring is non-linear."

"Due to the integrated spring and vibration damping structure commonly used in the front suspension, the spring needs to bear part of the lateral stress in the McPherson structure, which increases the reliability of the delicate air spring."

"In a double-wishbone structure, where the spring damper only takes up the longitudinal forces, the air spring is naturally much better off."

"And because of the existence of the upper and lower wishbone, and the articulated connection between the wishbone and the steering knuckle, the change of the front wheel inclination is still more linear and controllable, and usually the amplitude is smaller."

As the head of the chassis department, Xun Qi's professionalism is beyond doubt.

If you ask him to develop a part innovatively, he may not necessarily do it very well.

But if you work step by step, or explain some theories, there is absolutely no problem.

Cao Yang only set a requirement for the suspension of Xingchen 1 that the front and rear must be independently suspended, but it requires the use of air springs.

So Xun Qi needed to explain to Cao Yang the logic of the overall design of the chassis.

Previously, the technical requirements of each part have been set in the first version according to the requirements of the industry, and now it is time to implement each specific part.

Originally, everyone thought it was difficult to set the requirements for each part.

But now when I start designing parts, I find that there are many more difficult things waiting behind.

In the whole of China, there isn't any manufacturer capable of producing air springs, and Cao Yang doesn't want to import them from abroad and be slaughtered. As a result, Xun Qi's pressure on the chassis department will be greater.

"The air springs give the car height, ground clearance and spring rate adjustable characteristics."

"At the same time, we can seek better stiffness curves, vibration filtering performance, etc."

"By changing the amount of air in the airbag, the height of the vehicle body can be adjusted up and down."

"This is very important to the luxury of Star 1."

"Since the air spring is to be used, it must be equipped with a front double-wishbone independent suspension and a rear five-link independent suspension, so design according to this direction."

"Although these two suspensions are not used by mainstream models on the market, many models of BMW and Mercedes-Benz have chosen similar structures."

"The chassis department is first designed according to the structure of the BMW 730, and then it is tuned in a targeted manner."

"As for the air spring, I directly brought several designers to develop it together."

How to design some parts, Cao Yang will not interfere.

But some key parts are related to the commerciality of the entire model, so they must be installed.

Air springs are one of those things.

"Compared with ordinary steel springs, air springs have no noise caused by mechanical friction, and the air natural vibration frequency does not change with the increase of load, which is also more friendly to improving NVH performance."

"If Xingchen 1 is really equipped with air springs, it will really be very beneficial to improve the luxury of the model."

"Mr. Cao, don't worry, I will not lose the chain in terms of front and rear independent suspension."

Seeing that Cao Yang had taken over the most difficult air spring development work, Xun Qi naturally wanted to express his opinion immediately.

Otherwise, you can't do any work well, so what do you want?
"The development of the suspension and the adjustment of relevant parameters are very critical. If you encounter any problems, report them in time."

With so many tool people recruited, the work must be arranged.

Everyone develops the parts of the first version, and if Cao Yang puts forward some suggestions for improvement, it will be much more normal.

Otherwise, Cao Yang took out the blueprints for everything, not to mention unrealistic, and it seems very strange.

……

"Mr. Cao, judging from the software simulation data, the cooling effect of this air-conditioning system is at least [-]% stronger than that of Denso and Valeo's similar products, and compared with Keihin's air conditioner, it is half as strong .”

"I think it is completely possible to let Nanshan Auto Parts start the trial production of prototypes according to this drawing."

In the interior department of Xingchen Automobile, Peng Changyi faced the computer and explained the design plan of the air conditioning system to Cao Yang who was standing behind him.

Although various car companies rarely talk about air conditioners when they promote their models.

But anyone who has driven a car knows that if the air conditioner cooling effect is not good on a hot day, it is very uncomfortable.

For example, the Accord of Yangcheng Honda, although consumers have a high evaluation of it, they feel that the appearance and configuration are in line with the international market.

But in terms of the cooling effect of the air conditioner, there are a lot of complaints on the forum of Autohome.

Another thing that is comparable to the cooling effect is the noise.

Especially at high speeds, many people feel that the noise is loud.

What Star Motors is going to do is a luxury car, so the cooling effect of the air conditioner naturally cannot be the object of criticism.

Otherwise, no matter how much effort is made in the early stage of listing, it will easily ruin the reputation in the later stage.

"For the technology related to this air-conditioning compressor, remember to register the patent in time."

"The effect of our refrigeration system is good, the most important thing is that the performance of the air conditioning compressor is good enough."

This time, Cao Yang "developed" the air-conditioning main unit technology provided by Denso to Lexus. Compared with the current mass-produced products in the industry, the effect is naturally leveraged.

In fact, the operating principle of a car's refrigeration system is very simple, not unlike that of a household air conditioner.

The refrigerant that refrigeration relies on, that is, the form change of tetrafluoroethane, absorbs heat during the change process and reduces the temperature of the evaporator.

The compressor starts to drive the refrigerant to flow, and the refrigerant is pushed to the condenser to cool down, and then becomes liquid at the position of the drying tank and expansion valve.

When tetrafluoroethane becomes liquid, it will enter the low-pressure part, and the liquid refrigerant will enter the evaporator. The temperature of the evaporator must be higher than zero, and the boiling point of tetrafluoroethane is -26.2°C.

Obviously, the temperature of the evaporator is far above the boiling point of the refrigerant.

At this time, the refrigerant will boil instantly by absorbing the heat energy of the evaporator, and the evaporator will cool down due to the loss of heat energy.

Finally, the fan blows the hot air through the low-temperature evaporator, and the evaporator absorbs the air temperature to create "cold air", which is the cooling process.

It can be said that this principle is not complicated at all, and any parts company can understand it.

Even parts such as condensers, expansion valves, and pipelines have low technical thresholds, and many Chinese companies can produce them.

But for the air conditioner compressor, it looks simple, but it is actually very difficult to do well.

This time, the refrigeration system of Xingchen 1 works well because the air conditioner compressor is powerful enough.

"Mr. Cao, don't worry, the legal department now has dozens of people who are responsible for registering patents for various R&D departments."

"We have not only registered patents in China, but also registered patents in the United States, Japan, Korea, and the European Union."

"The more important the part, the more patents will be registered as much as possible, forming a patent barrier."

"In the future, if other component giants dare to sue us for infringing their patents, we can quickly find some evidence that the other party has infringed our patents, so that everyone will not dare to use patents against our company easily."

Peng Changyi obviously had special research on some of Cao Yang's work styles and requirements.

Star Motors wants to hold most of the core components in its own hands, and it is impossible not to infringe on other people's patents at all.

Even if it's not so obvious, if someone wants to sue you, they will definitely find something to do.

The countermeasure adopted by Xingchen Motors is to register enough patents by itself, and when the time comes to file a lawsuit, it will be a big pot.

I am the defendant and I am also the plaintiff.

Everyone spends it.

……

"Mr. Cao, Star Automobile Research Institute now has more than 1000 R&D personnel, can we temporarily control the pace of recruitment?"

Liu Youmei was also very busy during this time.

Nanshan Group has been developing rapidly and has a strong demand for talents.

This requires the human resources department to continuously carry out social recruitment, and even cooperate with headhunters to recruit some talents.

Dozens or even hundreds of people join the job every week, which makes Liu Youmei fully feel the pressure.

"What can a research institute of an automobile company do with only 1000 people?"

"Go and see the research centers of General Motors, Ford, Volkswagen, and Toyota. Which one has less than 1 people?"

"Although we don't need to compare with them in the short term, at least two thousand R&D personnel are needed to meet our design needs."

"The R&D and testing of components for each system requires a lot of talents."

"You just have to be bold enough to poach people."

Although many bosses of the company have complained about poaching people recently, Cao Yang has no intention of stopping.

The research and development centers of companies such as Spring City Motors and Xifeng Motors have raised many people, but they have not seen any decent results.

If I can make use of some of the capable talents, I can be regarded as contributing to the development of China's auto industry.

Automobile power, purely relying on the production of automobiles, there is no way to strengthen the country.

It takes all-round efforts from various parts to equipment to truly realize the power of the country.

Just like the efforts of Nanshan Special Steel, Nanshan Bearing, Nanshan Semiconductor Division and other fields, it will eventually affect all walks of life, so that the entire Huaxia industry can rise to a higher level.

Of course, this process must be very long.

After all, Nanshan is just a company, and it is very small when viewed in a country.

……

"Mr. Wang, I recently noticed that the number of patent registrations of Nanshan Group this year is the largest in the entire Lingnan Province."

"Even Warwick's number of patent registrations this year can't match them."

"This should have a lot to do with their large-scale expansion of the number of R&D personnel in the past two years."

"It is said that the entire Nanshan Group has more than 5000 engineers and technicians engaged in research and development."

"I think the company also needs to consider expanding the number of R&D personnel?"

Liang Chuanqing is also under a lot of pressure this year.

In addition to the F6 model, they are also developing two new models at the same time, one of which will be on the market in a few months.

The remaining one will be available next year.

However, during the development process, various difficulties were encountered.

So he has always wanted to expand the size of the R&D staff.

It's just that he also knows that BYD's overall profit margin is not particularly high, and the current number of R&D personnel is not too small.

If you continue to expand, there must be a good reason.

The large number of patents registered by Nanshan Group now provides him with a very good excuse.

"Before the emergence of Nanshan, Huawei was the most important enterprise in China that I have seen in research and development."

"I also know that R&D work is very important, but there must be a direct relationship between R&D and output, otherwise our company cannot support a large amount of R&D investment all the time."

"The number of R&D personnel is quite large now. If the second new model is also successful, I agree with you to recruit another 300 people."

Many parts of BYD's cars are purchased from suppliers such as Nanshan Group.

In the research and development of models, the number of personnel required is naturally not that many.

It's like developing a gearbox. If you want to do it yourself, you need at least a development team of 200 people before you can come up with something.

But if you buy the gearbox directly, it is enough to have a dozen or so people responsible for product testing and matching.

This is also the reason why the number of R&D personnel of domestic independent brands is generally not large at this stage.

From the appearance of the whole vehicle to each component, there are not many that are really designed by themselves.

Where do we need so many R&D personnel?
Selling a car means earning 2000 yuan. How can there be such a huge profit to support a large amount of research and development investment?
But if you don't have enough R&D investment, how can you achieve corner overtaking?
