All round car designer

Chapter 32
Zhou Fei was not joking. After traveling to the present world, not only the automobile industry has changed, but even the entertainment industry is very different from the previous life. Those classic singers and songs that Zhou Fei is familiar with cannot be found here. !

In other words, as long as Zhou Fei is willing, he can completely rely on writing songs for a living, and he doesn't need to be a hard-working Autobot like he is now.

However, Zhou Fei has his own pursuit. The sense of accomplishment brought by building a car is far greater than the sense of accomplishment brought by writing a song.

Zhou Fei now wants to pursue a more quality life, not just "looking at money". Cars can bring him everything he wants, but songwriting can't, at least Zhou Fei thinks so.

But since Chen Yunru likes to sing, Zhou Fei doesn't mind being her gold medal creator and a behind-the-scenes boss.

After returning to the dormitory, Zhou Fei was not in a hurry to fulfill his promise to Chen Yunru. It is estimated that the other party just thought he was joking at the moment. What's more, writing a song is only a matter of a few minutes, and Zhou Fei does not need to spend too much thought.

The top priority is to get the racing car out first.

The engine part is basically done, and it only needs to wait for the bench test on Xu Nan's side to fine-tune the relevant details.

Only the frame form and body shape need to be specially designed by Zhou Fei. The rest of the parts can be purchased directly from the market or specially customized.

So Zhou Fei wanted to determine these purchased parts and customized parts first, and finally design the frame slowly according to the size of these parts.

The first thing Zhou Fei has to solve is the choice of the front and rear suspension forms.

As a general term for all force transmission connection devices between the automobile frame and the axle, the function of the suspension is to transmit the force and torque acting between the wheel and the frame, and to buffer the impact force transmitted from the uneven road to the frame or body. , And reduce the vibration caused by it, so as to ensure that the car can run smoothly.

In a word, the suspension determines the ride comfort of the car. If there is no suspension, the car will immediately transform into a farm tractor, giving you the enjoyment of "car shock" anytime, anywhere.

From the structural point of view, the suspension is divided into non-independent suspension and independent suspension. The structural feature of the non-independent suspension is that the wheels on both sides are connected by an integral axle, and the wheels together with the axle are suspended by elastic suspension. Under the frame or body of the vehicle.

The rear leaf spring commonly found in commercial vehicles is the most typical non-independent suspension.

The independent suspension is just the opposite, and the wheels on each side are individually suspended under the frame or body through elastic suspensions.The emergence of independent suspension greatly reduces the impact on the body, and at the same time improves the ground adhesion of the vehicle. The characteristics of independent beating of the left and right wheels also greatly improves the driving stability of the vehicle.

The most common McPherson suspension in modern cars is a typical representative of independent suspension.

Due to the various disadvantages of non-independent suspension, it is rarely used in passenger cars, even in this world now, so Zhou Fei focused his attention on independent suspension.

After a rigorous comparison, Zhou Fei finally chose to equip the racing car with unequal-length double-wishbone independent suspension, and both front and rear suspensions have such a structural form!

The reason why Zhou Fei chose this type of suspension is entirely determined by the technical characteristics of the unequal-length double-wishbone suspension. Since the wheels on each side are hinged to the frame through the upper and lower cross-arms with unequal lengths, When the wheel moves up and down, the upper arm moves in a smaller arc than the lower arm.This will move the upper part of the tire slightly in and out with little effect on the bottom.

This structure is beneficial to reduce tire wear and improve vehicle ride comfort and directional stability, which is especially important in motorsports where high intensity and high speed coexist.

In particular, the advantage of improving directional stability not only reduces the possibility of safety accidents in racing cars, but may even become a big secret weapon for surpassing opponents!
After determining the structure of the suspension, Zhou Fei made a note in the column of the suspension in the notebook, and then set his sights on the brakes.

I don't know how long it took, until his stomach growled, and Zhou Fei realized that the sun outside was about to set. Looking at his phone, it was almost seven o'clock.

Stretching comfortably, Zhou Fei stood up from his seat, ready to forage for food first, and then finish the rest of the work when he came back.

Taking advantage of this afternoon, Zhou Fei has already selected the structural forms of key components such as suspensions, brakes, and hubs. Among them, the brakes and hubs need to be specially customized, but at present only the customized materials have been determined. Fei needs to cooperate with the follow-up frame design before making a decision.

As for the remaining parts, Zhou Fei will be able to confirm all of them within two hours at most.

Thinking about it now, it is not as difficult to complete the design of a racing car independently as I thought at first.

Next, as long as the design of the frame and body is completed, the assembly of the racing car and a series of tests can be carried out.

The days in the north are always shorter than those in the south. At this point, if it were my hometown, the sun would probably be about to set, but at this time in Spring City, there is only a sunset left, and there are more than ten In a matter of minutes, night will cover the entire city.

On the way to the cafeteria, Zhou Fei's mood has never been as happy as it is now. It turns out that it is really a very happy thing to concentrate on a job he likes.

Among other things, the satisfaction you feel when you complete a set goal really motivates you from the inside out and encourages you to move towards higher goals.

There are not many people on campus, but you can still see a few couples walking leisurely under the setting sun arm in arm, and Zhizhi is also having a final carnival before night falls.

sunset.

cicadas sing.

Shady alley.

Everything is so beautiful.

After dinner, Zhou Fei returned to the dormitory, first called home for more than ten minutes, and then sat in front of the computer again, ready to finish the rest of the work for the day.

In less than an hour, all the remaining work was done by Zhou Fei.

Regarding the matter of racing, that's all for today, but Zhou Fei is not idle. After changing his equipment, he came to the playground and started today's physical training.

Now that you have decided to become a racing driver, whether you are a professional or an amateur, your physical fitness must pass the test. Otherwise, once you enter the three top auto races under the FIA, whether it is F1 or WRC, Zhou Fei With his current physical fitness, he might not even be able to move the steering wheel when making a sharp turn.

So after returning to school, Zhou Fei has already started exercising consciously.

After finally running five laps, Zhou Fei could not wait to lie on the ground directly.

Many people have been in college for four years, and their physical fitness is getting worse every year. Sometimes they even get out of breath when they climb the stairs, let alone run five laps around the playground.

The decline in physical fitness, in addition to the credit of the game, I am afraid that the girl with ten fingers also contributed a lot.

After walking slowly around the playground for another two laps, Zhou Fei returned to the dormitory and took a warm shower comfortably. Seeing that it was still early, Zhou Fei picked up his phone, and after thinking about it, he sent a message to Chen Yunru,
"I wrote a song for you, how about you sing it to me?"

After sending, Zhou Fei just hugged his phone and began to wait for the other party's reply.
