Chapter 189 Go! Way to greatness!

The train has started.

As the cold and sluggish electronic synthesis sound fell, the two headlights on the front of the car instantly lit up, directing the front.

In the cab, many virtual projections also appeared out of thin air, displaying various icons and data that Chen Yu could not understand.

Sitting in the driving seat, Chen Yu looked at the rows of screens and joysticks on the left and right armrests, and asked, Is there no steering wheel and accelerator?

The entire train is operated by touch. The electronic voice replied.

Tell me how to do it.

Manual mode \u0026 smart mode?

Chen Yu hesitated for a moment: The manual mode has a sense of control, let's introduce the manual mode first.

Yes, the train conductor. The third-level engineering vehicle of the maglev general construction is divided into two sets of operating systems. In the passing state, the moving mode is superconducting magnetic repulsion (EDS). Strong magnetic field is repelled, and the special long stator synchronous linear motor is controlled by artificial intelligence to complete the energization of the three-phase winding of the stator, and the moving magnetic field is generated to interact with the suspension (excitation) of the train to complete the traction...

During the explanation, the artificial intelligence second product also intimately showed a set of dynamic videos.

In the video is a working principle diagram of a long stator synchronous linear motor. The complex circuit and line diagram contain many professional terms such as pole pitch, stator laminations, stator windings, linear generator windings, and field windings.

I'm afraid Chen Yu won't understand.

Chen Yu raised his legs in thought, maintaining the posture of a wise man, sometimes thinking deeply, sometimes nodding, sometimes pinching his chin, sometimes sliding the crystal ball...

Because there are many stages in the motor, the number of slots per pole and phase is q=1; in order to facilitate the arrangement of windings...

...Since the number of slots per pole and phase is q=1 and the uniform air gap is adopted, the harmonic magnetomotive force of the stator teeth is relatively large, and the driver should pay attention to the changes in current density, rated voltage and rated current of the excitation device when applying power. ...

...Standard calculation example: The length of a car of a maglev train is 23.32 meters, the total weight is 107.6 tons, the ultra-low speed stage is 400 kilometers per hour, and the running resistance is 60.22kN...

...The parameter values ​​calculated so far are: at 75 degrees Celsius and 215Hz, the resistance of each phase of the stator in the 300M power supply section is 0.2886Ω (omega), and the stator leakage reactance is 21...

【What? What? What? 】

[What are they talking about? 】

[Sit in rows under the tree in a daze. 】

【It's great, it's wonderful. 】

【devil……】

[I don’t understand, skip it. 】

[I always feel that the UP master's evaluation is getting more and more unfriendly. 】

[Junior high school maths so much I don’t understand? 】

[Isn't it primary school mathematics? 】

[Looking at the anchor's pensive look, he must have understood. 】

[Nonsense, those who can do technology evaluation must have a full level of professional knowledge. 】

[Awesome...]

[Awesome +1. 】

Five minutes later, the obscure control principle and control method were finally introduced.

Chen Yu turned his head and looked at Xiao Taohong: Do you understand?

Ah? Xiao Taohong looked blank.

well.

Sighing, Chen Yu stood up and patted Xiao Taohong on the shoulder: You can't always think about playing, you have to learn more. You listen to it a few times and try to start it. I'll go out to get some fresh air.

With that said, Chen Yu shook the non-existent dust on the dragon clothes, walked out of the cockpit with his hands behind his back, and left the camera inside.

After entering the living area to solve the three urgent problems, Chen Yu lay on the sofa and rested for five minutes. Guessing that the official people were coming soon, he got up and went back to the cab.

In front of the crystal ball, Xiao Taohong was still listening to the artificial intelligence explanation with her eyes dazed.

Do you understand? Chen Yu asked.

Ah? Xiao Taohong looked blank.

Forget it, this knowledge is still too profound for you, take your time. Chen Yu waved his hand and looked at the camera: More than ten minutes have passed, and the introduction of this maglev three-level general construction vehicle has been received Here it is. Next, we will directly start the actual operation and evaluation.”

After finishing the words, Chen Yu walked to the giant car window and looked out, and saw police cars, helicopters, and camouflage jeeps all coming, densely parked around.

Since Chen Yu was not wearing protective clothing, it was impossible for Chen Yu to be exposed to the outside world at will, so he ordered Xiao Taohong to say, Go outside and find the person in charge, and bring the cooperation intention and the things the other party gave you.

good!

Xiao Taohong nodded heavily, trotted out of the cab, got off along the first carriage, stood on the snow with her hands on her hips: Who is your person in charge?

It's me, it's me! I'm in charge here for the time being! A young man hurriedly came over, nodded and saluted: Hello ma'am.

Now I am the father-in-law. Xiao Taohong pointed to the eunuch uniform on her body.

Grandpa... Gonggong... The young man was on the spot in astonishment.

Hmm. What do you have for me?

Looking at the not very smart girl in front of him, the young man wanted to say something, but recalling the order from his superiors, he held back abruptly and handed out the small box in his hand: For Mr. Wang's cooperation that benefits the country and the people this time, Thank you very much. Please tell Mr. Wang that the whole of China will unconditionally support his maglev construction plan.

Okay, I'll pass it on. After taking the box, Xiao Taohong waved her hand, stepped onto the train and closed the door.

call……

Taking a breath, the young man took a few steps back, looked at this maglev engineering vehicle, and smacked his lips enviously...

...

My king, here you are.

Um.

Taking the box from Xiao Taohong, Chen Yu opened it with his back to the camera.

On the top layer is a handwritten thank you letter with many stamps printed at the end of the letter.

He read the thank-you letter carefully, put it aside, and picked up the lower file bag.

Tear!

Open the seal, pull out the stacks of documents in the file bag, and find that these are detailed construction plans, including site selection, geological structures along the way, difficulty of excavation, and other information.

There are three roadmaps, and Chen Yu is recommended to refer to them.

After carefully reading all the documents, Chen Yu chose the second route among the three routes, from the capital city of Pingchang directly to the magic city of Puqing, without any transfer stations along the way. It's a straight line.

After making a decision, Chen Yu closed the lid of the box, picked up the route plan and sat in the driver's seat, saying loudly, Second goods.

I am here.

Turn on the smart mode and go to the Pingchang District of the capital.

Sorry, your destination location cannot be recognized, please manually select the destination coordinates.

The electronically synthesized sound echoed, and a virtual projection appeared half a meter in front of the driver's seat, showing a two-dimensional map.

After observing for a while, Chen Yu found out the location and clicked on a certain point in Pingchang District.

Path planning.

The path has been planned, it has deviated from the road, and it is being corrected.

boom……

Accompanied by a loud rumbling noise, the nearly 300-meter-long behemoth began to vibrate.

Outside the train, everyone felt the numbness from the soles of their feet.

This is the power of machinery and technology...

Boom boom boom!

Half a minute later, the bottom of the train was originally flat, and rows of track chains sank.

These crawler tracks have sharp spikes raised on the surface to enhance friction with the ground. In the track, there are driving wheels, supporting wheels, guide wheels and supporting sprockets.

More like a tank than a train.

Quack quack quack...

Under the force of countless driving wheels, the huge body moves forward slowly.

The barbed tracks rubbed against the snow, making a strange sound that made the teeth ache and the scalp tingle.

Is this... still a weapon?

The young person in charge raised his head, looked at the giant steel beast in front of him, and muttered to himself.

In the cab, feeling the movement of the car body, Chen Yu rubbed his hands excitedly, and pointed straight ahead: Accelerate! To the great route!
