Chapter 620 Phase Two
second stage?

And the second stage?

The first stage is already so awesome, so to what extent can the second stage be so awesome?
It's unbelievable.

Shuai Shuai carefully looked around.

There are no other cars.

Do you still use this car?

Sure enough, in the next second, a group of professionals rushed to the side of Yemu 301 and unloaded some equipment.

That's right, it was removed.

I'm going to carry out the second set of tests. Shouldn't it be to install some equipment?

What do you mean by uninstalling the device?
With a big eye, Qin Feng knew everyone's doubts.

Qin Feng didn't give a shit about it, so he went on to say:

"That's right, this car is still used in the second stage, and, after the final test is over, this car can still drive, this time the test is considered qualified."

Having said that, Qin Feng pointed to the equipment that was being unloaded, and said slowly:
"Actually, the Yemu 301 cars sold on the market do not have these restrictive devices. These restrictive devices have only one function - to cut off the control of the car by the central control system. Only in this way can we ensure that the car hits the test car in front. wall."

what?
This time, everyone reacted.

Only after it is cut off can it be guaranteed that the car will hit the test wall. Does it mean that if it is not cut off, the car will not hit the test wall?
Soon, professionals disassembled the equipment, and then, after replacing it with a new dummy, the test of the car began again.

second stage.

Everyone only saw the car return to its original position again.

It's still the same car, and it's still the same car test wall.

The car started again at high speed.

This time, many people are counting the seconds.

When the car reached a hand speed of [-] kilometers, everyone began to realize that the whole process took only [-] seconds.

[-] seconds, from zero to [-] kilometers per hour.

This has been achieved to the highest level of racing.

Could it be that Yemu Group is able to produce professional racing cars?
You know, racing cars are not that easy to produce.

So far, there is no domestic manufacturer capable of producing formula racing cars.

At least, not on the surface.

As for whether it actually exists, the outside world does not know.

However, it can be seen now that Yemu Group seems to have this qualification.

Racing, as we all know.

Motorsports Motorsports are divided into two categories, track racing and off-track racing.The origin dates back more than 100 years.The earliest racing competitions were carried out on the roads between cities.

Later, many drivers died because of the great danger of road racing, so professional racing tracks came into being.

That said, motorsports are divided into two broad categories, track racing and off-track racing.

Field racing, as the name suggests, means that racing cars compete in a prescribed closed field.It can be divided into drift races, formula races, car races, sports car races, GT endurance races, short-track rally races, off-road races, and straight-line races.

Non-field racing, basically the competition venue is not closed, mainly divided into rally, cross-country and mountain climbing, beach racing, mud racing and so on.

The formula race also includes Formula One, Formula Three, GP2, F3000, Indy Car, Sam's Champion Formula, Ford Formula, Combas Formula and go-karts.

The focus here is on formula racing.

At least, the formula car looks a bit more official.

Formula racing This is a type of car racing.Racing cars must be manufactured in accordance with the procedures stipulated in the vehicle technical regulations issued by the International Automobile Federation, including body structure, length and width, minimum weight, engine working volume, number of cylinders, fuel tank capacity, electronic equipment, distance and size of tires, etc.

FIA requires F1 racing cars to use engines with a displacement of 1.6L, 6 cylinders and superchargers.

The chassis of the F1 racing car is made of carbon fiber, which is very light and strong.

The chassis of the car is very low, with a minimum ground clearance of only 50-70mm.Compared with ordinary cars, F1 racing cars have many unique features. Its body is slender and long, its body height is very low, and its wide wheels are extremely conspicuous and completely exposed, so-called "open wheels".

Every F1 racing car is an elaborate masterpiece of world-renowned automobile manufacturers.The value of a racing car of this kind exceeds 700 million US dollars, which is no less than the value of a small aircraft.

The F1 car competition is not only a competition of courage, driving skills and wisdom of racers, but also a competition of science and technology among major automobile companies behind it.

The new racing car launched in the car competition embodies the painstaking efforts of many developers from design to manufacture, and represents the latest high-tech level of a company or even a country.

Automobile competition is also a contest of the quality of scientific and technological talents in various countries.It is reported that there are more than 2000 professionals directly engaged in the design, manufacture and research of racing cars in Japan, and about 1 people in the United States; while Puppy Plaster Country has the most, estimated at nearly 2 people.

But now, how many people are there in the Yemu Group?
It seems that the number of people in the night car is less than 2.

Of course, this does not mean that the current Yemu Group has the qualifications to manufacture Formula One cars.

You know, the manufacture of Formula 1 cars is not just about engines.

There are various other sections.

For example, the site in the big piece.

The chassis is used to support and install the engine and its components and assemblies to form the overall shape of the car, and receive the power of the engine to make the car move and ensure normal driving.

It consists of four parts: transmission mechanism, running mechanism, steering mechanism and braking mechanism.That is to say, except for the engine, tires and body shell, almost all are included in the scope of the chassis.

The restrictions on the chassis of the F1 technical rules mainly include: manufacturing materials, size definitions and safety test indicators.

The maximum overall width of an F1 vehicle body shall not exceed 1400 mm, and there is no limit to the length; the total height of the vehicle body shall not exceed 950 mm, and the width between the centerlines of the left and right wheels shall not exceed 1400 mm.

The overall width of the rear wing is 950 mm.The distance from the axis of the front wheel to the front edge of the front wing shall not exceed 1200 mm, the axis of the rear wheel to the rear edge of the tail shall not exceed 500 mm, and the total height of the tail shall not exceed 800 mm.

The safety test is mainly aimed at the cockpit and the front and rear of the car, among which the safety impact test for the cockpit is the most stringent.
It is required that the side of the cockpit must be able to withstand the impact of a steel sheet with a diameter of 300 mm and a mass of 780 kg at a speed of 10 m/s at an angle of 90 degrees.

The monocoque with a total mass of 780KG is bound to the bracket, and when it hits the concrete wall vertically at a speed of 14 m/s, it must be able to ensure that the cab is intact.

In terms of safety, it seems that the Yemu 301 car of the Yemu Group has fully met the requirements.
