Latest URL: "The train has started up."

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

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

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

"The whole train is operated by touch." Electronic voice replied.

"Tell me about the operation method."

"Manual mode & smart mode?"

Chen Yu hesitated for a moment: "The manual mode has a sense of control. Let me introduce the manual mode first."

"Yes, the conductor. The maglev general construction three-stage engineering vehicle is divided into two sets of operating systems. In the current state, the moving mode is superconducting magnetic repulsion (eds), which cools the superconductor at the bottom of each car, and it is in phase with the electromagnetic track. Repelling the strong magnetic field, artificial intelligence controls the extra long stator synchronous linear motor to complete the energization of the three-phase stator windings, generating a moving magnetic field and acting on the suspension (excitation) of the train to complete traction..."

During the explanation, Erhuo also showed a group of dynamic videos intimately.

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

I was afraid that Chen Yu would not understand.

Chen Yu thoughtfully, raised Erlang's legs, 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 motor stages, take the number of slots per pole per phase q=1; in order to facilitate the arrangement of windings..."

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

"...Standard calculation example: One carriage of a maglev train has a length of 23.32 meters, a total weight of 107.6t, an ultra-low speed stage of 400 kilometers per hour, and a running resistance of 60.22kn..."

"...The parameter values ​​calculated so far are: at 75 degrees Celsius and 215hz, the stator resistance per phase of the 300m power supply section is 0.2886Ω (Omega), and the stator leakage reactance is 21..."

【What? What? What? 】

[What are you talking about? 】

[Chuddled to sit in rows under the tree. 】

[It’s great, it’s wonderful. 】

【devil……】

[Do not understand, skip it. 】

[I always feel that the evaluation of the up master is getting more and more unfriendly. 】

[Junior high school mathematics you don’t know so much? 】

[Not elementary school mathematics? 】

[Looking at the meditative look of the anchor, I must understand it. 】

[Nonsense, those who can do science and technology evaluation must have full professional knowledge. 】

[Great...]

【Great +1. 】

Five minutes later, the obscure control principles and methods are finally introduced.

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

"Huh?" Xiao Taohong looked blank.

"Ugh."

After 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 should listen to it a few times and try to start it. I'll go out to get some air."

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

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 person was about to come, so he got up and returned to the cab.

Before the crystal ball, Xiao Taohong listened to the artificial intelligence explanation with dumbfounded eyes.

"Understand?" Chen Yu asked.

"Huh?" Xiao Taohong looked blank.

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

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

Since Chen Yu didn't wear protective clothing, it was impossible for Chen Yu to be exposed to the outside world at will, so he instructed Xiao Taohong to say: "You go to the person in charge outside, and bring in the intention of cooperation and everything the other party gave."

"it is good!"

Little Taohong nodded heavily, ran out of the cab, got off the first car, and stood on the snow with her arms akimbo: "Who is in charge of you?"

"It's me and me! I'm in charge here for the time being!" A young man hurriedly came over and nodded in salute: "Hello Madam."

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

"Father... Father..." The young man was stunned on the spot.

"Hmm. What do you want to give me?"

Looking at the girl who seemed "not too smart" in front of him, the young man wanted to talk, but recalled the order from his superiors, he abruptly held back, and handed out the small box in his hand: "For Mr. Wang's cooperation to benefit the country and the people, Thank you very much. Please tell Mr. Wang that All China will unconditionally support his maglev construction plan."

"Okay, I will pass it on." Taking the box, Xiao Taohong waved her hand and stepped onto the train and closed the door.

"call……"

After taking a breath, the young man took a few steps back, looked at the maglev engineering vehicle, and smacked his lips with envy...

...

"My king, here you are."

"Ok."

Taking the box handed by Xiao Taohong, Chen Yu turned his back to the camera.

At the top level is a handwritten thank-you letter with many stamps at the end.

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

"Tear!"

He opened the seal and pulled out the stacks of documents in the portfolio, and found that these were detailed construction plans, including site selection, geological structure along the way, difficulty of excavation, and so on.

There are three roadmaps, and Chen Yu is recommended for reference.

After earnestly taking all the documents, Chen Yu chose the second of the three routes, from the capital of Pingchang to Puqing, the magic capital, without any transit stations along the way. It is a straight straight line.

After making a decision, Chen Yu buttoned the lid of the box, picked up the route plan and sat in the driving chair, and said loudly, "Second goods."

"I'm here."

"Turn on the smart mode and head to the Pyeongchang District of Beijing."

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

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

Chen Yu observed the location for a moment and then clicked on a certain point in Pyeongchang District.

"The path is being planned."

"The path planning is completed, it has deviated from the road surface and is being corrected."

"boom……"

Along with the rumbling noise, the behemoth nearly three hundred meters long began to shake.

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

This is the power of machinery and technology...

"Boom boom boom!"

Half a minute later ~www.readwn.com~ The bottom of the train was originally flat, and rows of track chains were sunk.

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

It is more like a tank than a train.

"Quack quack..."

The huge body slowly moved forward under the power of countless driving wheels.

The barbed track rubbed against the snow, making a strange noise that made teeth sore and scalp tingling.

"This... is 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 body, Chen Yu rubbed his hands in excitement, and pointed straight ahead: "Speed ​​up! To the great route!"
