Chapter 129
The chassis of a car determines the grade of the car.

Whether a car runs smoothly, whether the brakes are sensitive, whether the control is smooth, whether the transmission is timely, whether there is noise when running, all have something to do with the chassis.

After Xu Fei's first experiment failed, according to the engine layout provided by the mechanical engineer, with the help of the basic production line, he manufactured a variety of large wind-up cars again.

Then remove the casing and start the chariot to crush...

After working for a whole morning, I finally got a set of semi-finished products that I was satisfied with.

Different from the metal cabinet chassis of the chariot, it is a set of 'I'-shaped metal frame made of high manganese steel alloy.

Due to the full-time four-wheel drive scheme, the front end of the word "工" is called the steering drive axle, the rear end is called the drive axle, and the middle is called the drive shaft.

According to the "suspension" scheme designed by the mechanical laboratory, it borrows the structure of the mechanical legs of the terrifying spider, and uses five linkages + the stabilizer in the fire control system of the tank at the front and rear.

For example, when a car is driving at high speed and turns left or right suddenly, the four wheels are constantly changing posture under the action of the stabilizer bar and independent suspension, making the body like a chicken head, no matter how it runs, it is always at the same level. Avoid risk of rollover.

According to the simulated data given by the built-in computer of the basic production line, the Elk tested 90km/h, directly killing the world's number one Citroen V6 at 85km/h.

However, Xu Fei only recently discovered that the computer at the base is deceptive.

The parameters of the assembled version of M8 are exactly the same as those of the Grizzly.

But in the battle between the two, the Grizzly Chariot might not be able to fight five M8s.

Especially in the "Drag Racing Shooting" section, the assembled version of the M8 was manipulated by Malaysia, and several bolts collapsed, and the turret was crooked...

Therefore, the data of the car chassis simulation test can only be used as a reference.

The real effect needs to be tested.

After eating two steamed buns at noon, everyone continued to work.

With the chassis and suspension, the next step is to design the wheels and tires, measure the diameter, tire pressure, section, grip...

In addition, the No. 1 mechanical laboratory designed the 'explosive airbag', first dismantling the terrorist robot, extracting a small amount of fraudulent medicine from the super-large boom~, and then using fiber materials to make a compressible airbag... After the chip is activated, the fraudulent medicine is ignited Explosion, causing the airbag to inflate instantly.

However, after it is produced, various crash tests need to be carried out, which will be discussed later.

No. 2 mechanical laboratory design gear, center console shell...

No. 1 electrical laboratory designs circuits, audio, lighting...

No. 2 electrical laboratory, dismantling the chariot radio, making a player...

Engineers who were not stationed in the mechanical laboratory disassembled other terrorist robots and integrated radar and infrared equipment...

Since only one prototype was built, all projects moved quickly.

In less than an hour, Xu Fei got an ugly frame version of Hongqi.

The body has not yet been designed, and there is no length, width and height data for the time being.

However, according to the specifications of the chassis, it is speculated that the length is not less than 6 meters, the width is at least 2.1 meters, and the height will reach 1.6 meters.

After completing the above, the next step is to conduct a crash test to test the upper limit of energy absorbed by the frame and the protective effect of the airbag.

The test is divided into two parts.

One is active collision.

Produce a rubber man to act as a driver, and use a small gantry crane to send the prototype to the large crawler of the chariot factory. The set speed is 28 m/s, about 100 km/h.

Then drive a Rhino heavy tank, placed across the end of the track.

The moment it started, the prototype car was sent out by the track like a bullet...

The modules that come with the base never disappoint.

The moment the front of the car hit the Rhino heavy tank, the steering wheel boomed, and three orange-red airbags popped up, sending the rubber man and the driver's seat flying out...

The body frame made of high manganese alloy, except for deformation, has not been smashed, and obviously does not have much energy absorption effect.

In other words, the harder the frame, the worse the energy absorption effect. On the contrary, the frame that is easy to break can help the occupant absorb the impact energy.

Of course, the body of the car must be hard, otherwise it would be embarrassing to run into a rear-end car with a low-end car one day.

After the first round of testing, the engineers sent the damaged prototype to the maintenance workshop.

With the support of the laboratory, the mechanical and electrical devices of the outside world can also be repaired here. However, engineers need to beat them in person, instead of sending them to the workshop for a period of time like the Grizzly Chariot and Rhinoceros Chariot. Can get a new one.

After half an hour.

The second round of testing begins...

after an hour.

The third round...

two hours later.

Fifth round...

for a long time.

Proceed to the second link.

That is passive collision.

Put the sample car horizontally at the end of the transmission, and then use the conveyor belt to send the Grizzly Chariot out...

A 20-ton iron bump hit the prototype car, and the latter popped up the airbag instantly...

then.

Second round of testing...

The third round of testing...

The fun of engineering men is often so unpretentious and boring...

In order to facilitate the test, Xu Fei took a break from his busy schedule to greet several engineers and assemble several prototype cars again.

The No. 1 prototype was scrapped, its parameters were recorded, and it was sent for maintenance.

The No. 2 sample car adjusts the parameters and conducts the test...

The No. 3 sample car is ready to go...

Wait until evening.

The leader of Dongshan Development and Reform University called.

"Crooked? Uncle Liang."

"Xiao Xu, did you use a special channel?"

"That's right, let's hire some auto professionals."

"How many? More than 300 people, the higher-ups specifically called me and asked: What do you want to do?"

"So much?"

"You do not know?"

"I really don't know. Didn't he just become the director of Hongqi factory? He wanted to set up a new company, but he didn't even have any technicians, so he contacted James, the chairman of TEP (North America), and asked him to help with the recruitment. Digging."

"You find a way to get the identity information of this group of people."

"Uncle Liang, I'm very busy. Besides, where can I get it done?"

"I've been criticized...Wait, you said you're the director of Hongqi Factory?"

"hold head high!"

"When did this happen?"

"It was just finalized the day before yesterday, and it is estimated that we will receive a notice a year ago."

"Separate from FAW and reorganize Hongqi?"

"Correct."

"Are they willing? You know, there are high subsidies every year."

"I heard from Lan Feng that the subsidies in recent years have been used on the Audi A6, and it is impossible to allocate new subsidies in the future."

"That's it...well, I see."

"How to deal with the people I dug out?"

"You first find a way to get them into the job, and then come to me and apply for a work visa."

"Thank you, Uncle Liang."

"Remember to go back and help me get another batch of advanced production equipment."

"Middle, next time I will move the Daewoo General Factory here."

"Then you don't have to."

Xu Fei hung up the phone, thought for a while, and contacted Lan Feng.

"crooked?"

"What's the matter, Xiao Xu?"

"Leader, the sample car has arrived, people have been recruited, and the production line is already on the way. When will we reorganize Hongqi?"

"..."
