Siheyuan: Heavy Industry Revitalizes the Country

Fang Xiang, who was just lying in the dormitory, did what he said.

He jumped off the bed and ran straight to the office of the research team.

"Junior Brother Fang, why are you here?

Didn’t the professor tell you to go back and rest? "

When I arrived at the office, Cao Tianwei and his team members were all there.

"Oh, you're still blaming me. Didn't the professor tell you to go back and rest?"

Fang thought for a moment and saw that these guys were at war again.

But you still have to say what you need to say.

"We are just holding a meeting to do some ideological work for everyone."

Cao Tianwei chuckled and didn't explain much.

"Since no one is leaving, I'll draw a picture of the exterior first, and you can criticize it."

Fang Xiang also smiled. If you don’t want to leave, then don’t leave. Just get straight to work.

"Okay, I'll get you the blueprint."

"I'll get you the tools."

Soon, blank drawings, paper, pen and other tools were placed on Fang Xiang's desk.

The appearance drawing is actually the easiest to draw among all the car drawings.

If you want to be lazy, you can just sketch out the lines with a few strokes, and then a simple concept map will come out.

Although Fang Xiang had a complete appearance diagram, there was no need to take it out now.

Naturally, the shape and size of the Wrangler were drawn using the simplest line drawings.

"Wow, this car is really beautiful."

"This is so beautiful. If it's for takeout, I would also like to buy one."

"It's definitely not for takeout. This is a controlled item. We might as well wait for an allotment."

"We will definitely have to make a prototype car, so why not stay here when the time comes?"

"I think it's okay. We can leave the sample cars here so that we can drive them out."

"Drive it out? That's wishful thinking. The car doesn't have the necessary documents. At most, you can just have some fun on the Shuimu campus."

"It's okay to have fun on campus. Which man wouldn't love such a beautiful car?"

"That's right, if I could have a car like this in my life, it would be worth dying for."

"Tsk, you've achieved so much that even your death is worth it. Can you be more ambitious? Let the country reward you with one!"

"Yes, yes, yes. If we can really build this car, the country will definitely reward us."

"Well, I'm more practical, just give me a house."

As everyone discussed it, four exterior drawings had been completed.

Front, side, back and top views.

"Brother Cao, the professor should still be here. Do you want to show it to the professor?"

Cao Tianwei held a side view in his hand and couldn't let it go.

Fang Xiang saw that the team members were still discussing, so he made a suggestion.

"Let's go, let's go now."

Cao Tianwei immediately came to his senses, stopped admiring, picked up a few other drawings, and took Fang Xiang away.

After a while, we arrived at the professor's office.

"Professor, Fang Xiang drew a picture of the exterior. Would you like to take a look?"

Cao Tianwei spread the drawings on his desk.

"Four meters and seventy-five long? Fang Xiang! You are kidding!"

Professor Xu looked at the drawing and was about to start praising it when he suddenly noticed the dimensions marked on the drawing.

He immediately started scolding.

"This is the car the army wants, why did you make it so big, 4.75 meters?

Do you know how much it would cost if it was this long?

Such a large size will greatly reduce its practicality.

Moreover, the weight must be more than 1.8 tons. Isn't this a waste of steel?

The weight is increased, but the engine horsepower is so small, can it pull the vehicle?

The domestic road penetration rate is so low, the smaller the car, the larger the scope of application and the lower the cost.

How come you don’t even understand this?”

Professor Xu's saliva was almost spraying onto Fang Xiang's face.

Fang Xiang suddenly remembered that this Wrangler was a civilian car model of later generations.

Nature is based on comfort and practicality, but it does not meet today's requirements.

I didn't think about the size at the time and just copied it.

Now, I got scolded for nothing.

“Take it back and redraw it!

Remember, even if the chassis is lengthened, the size of the vehicle cannot exceed four meters and one meter!

Also, don't make it a hard top, want a removable soft top that can be converted!

The front windshield should be able to be folded flat.

The total weight should be controlled within 1.6 tons, preferably around 1.5 tons.

Hmm...it looks good, let's take this one."

Professor Xu's voice almost shattered the glass in the office.

However, the last sentence still affirms the appearance design.

It's nothing more than that there are strict requirements on size.

"Okay, I'll change it now."

Fang Xiang lowered his head, admitted his mistake, and quickly ran away with the drawings.

"I'm sorry, Senior Brother, I made you get scolded along with me."

After going out, Fang Xiang stuck out her tongue at Cao Tianwei.

"It's okay, it's okay. We were just too excited and missed such important data.

Let’s go back and redraw it.”

Cao Tianwei patted Fang Xiang on the shoulder and comforted him.

"Well, redraw it."

Fang Xiang nodded.

After returning to the office, I took out the new design drawings.

Plan the size first.

The length, width and height are set at 4080mm*1820mm*1870mm.

The structure is still four doors and five seats, and the wheelbase is estimated to be about 2320.

This makes the rear space no longer so cramped.

Considering that only 14-inch tires can be used.

There is no way to design the approach angle and departure angle to be large enough.

The climbing angle will be slightly smaller than 212, and can only reach a maximum of 42 degrees.

Finally, the suspension still uses a longitudinal leaf spring non-independent suspension.

Of course, according to the boasting I made to Mr. Hu today.

The double-jointed arm steering tie rod was replaced and a lateral stabilizer bar was added.

And the installation direction of the rear shock absorber was adjusted.

After I finished painting these, it was already dark.

After eating the dinner Cao Tianwei called, Fang Xiang went back to the dormitory to rest.

The remaining drawings will have to wait for the complete drawings of 212 to arrive.

After a night's rest, the complete drawings of 212 were sent to Shuimu as agreed.

Fang wanted to continue the design work.

Except for the design flaws mentioned in front of Mr. Hu, all have been adjusted.

According to Professor Xu's requirements, we designed the body structure and chassis first.

As for the body structure, it is actually not too complicated or difficult.

What's more, there are drawings of Wrangler and 212 in front.

Not to mention copying, at least after comparison, the work was completed very quickly.

Next is the chassis, which is non-load-bearing as a whole.

So the structure is also very simple.

Because we have to consider the cost and the material processing technology must be in line with the current domestic level.

In addition to lengthening the chassis of the 212, Fang Xiang also made substantial optimizations.

To improve the vehicle's survivability in harsh road conditions.

All parts of the vehicle chassis are designed to be very strong and sturdy.

To adapt to the off-road sections that the troops need most.

The vehicle spares no effort in enhancing the suspension rigidity and sturdiness of the front axle.

Just to improve the vehicle's survivability in harsh road conditions.

As for things like unsprung mass, they are not within Fang Xiang's consideration.

The vehicle's steering rod is also designed to be exceptionally strong.

Its diameter is even close to that of the newly added anti-roll bar.

In order to cope with more special steering forms and harsh road conditions when off-roading.

An additional steering damper is provided between the steering rod and the axle.

To avoid the problem of the steering wheel hitting your hands in extreme situations.

At the same time, the vehicle's shock absorber springs adopt a long-stroke design as much as possible.

The purpose is to effectively improve the comfort of the vehicle.

Then some minor optimizations were done.

The vehicle's beams, reinforcement ribs and other solid structures can provide more protection for the chassis.

Important components of the vehicle, such as the drive shaft, exhaust pipe and fuel tank, are located above the beam.

Therefore, even if the bottom is dragged, these important parts will not be damaged.

Moreover, in addition to the crossbeam, multiple reinforcing ribs are designed to ensure the chassis rigidity of the vehicle.

The previous straight exhaust has been changed to a curved exhaust pipe design.

This is to prevent water from flowing back into the exhaust pipe when the vehicle is driving through water.

Finally, the optimized new chassis is compared with the 212 chassis.

It is not an exaggeration to say that there is a world of difference.

But consider the cost issue.

Fang Xiang also specifically noted which newly added optimization items could be canceled or have their specifications lowered.
